The Pandora connectors and the Beagle Board connectors are *very* different. So I see the only method to connect the Beagle to the Pandora is through USB.

Which option would you prefer? Since this are too many for us to handle, please let us know the variants you like. We will then decide which ones we will finally produce. To simplify the answers, please vote here: http://www.doodle.com/huagbg7hu94zyame Ok, I think this poll already made clear that most of you are interested in a completely assembled offer (for software development). And a fresh LCD module would help to save disassembling a Freerunner (unless you have a broken one that is being covered by dust). So we drop the kit approach but keep the bare PCB just in case someone wants to have it. The other question gives a strong preference for GPS. We are still waiting to receive some components to verify that it (still) works on the new PCBs (this is in fact the second generation - the first one was done earlier this year). Nevertheless, you can already look into the data sheets of the W2SG004: http://www.wi2wi.com/products/datasheets/W2SG0004_Datasheet_Rev1.81.pdf And how to control the GPS receiver and antenna switch from user space: http://projects.goldelico.com/p/gta04-kernel/page/Devices/ Comments and contributions to the project pages are welcome.

A few weeks ago Sparkfun announced a new 3-axis gyro with I2C (IDG3200), which would make the Naviboard much simpler, I guess, and give the chance to add the pressure sensor (BMP085) to the PCB. These are interesting chips. To disclose a top secret: the OM Beagle Hybrid also has space for up to 1x ITG-3200, 2x LIS302, 1x HMC5843, 1x LSM303 (redundancy), and 1x BMP085, all connected to I2C2 of the BeagleBoard. In addition to the TSC2007 and a Wi2Wi GPS module. Let's cross fingers that at least some of them work :) I have one of these gyro on a breakoutboard in my hands, the chip is really tiny with a tiny tiny footprint. I think I will be able to solder the pressure sensor with a reflow oven in future (when my reflow oven is finished), but this gyro and the honeywell mangneto sensor. How do I solder them? How do I apply the solder paste to such a fine grid with no special epipment? You said, you also have at least one chip with BGA (0.5 pitch I guess) on your board, how did you manage to solder this during prototyping? Any tipps? Anyone? Christoph has already described one method that can be applied during prototyping. For the Beagle Hybrid, we did go to our SMD company and they have equipment to solder that for single parts.

You said, you also have at least one chip with BGA (0.5 pitch I guess) on your board, how did you manage to solder this during prototyping? Any tipps? Anyone? Well, I reflow soldered the HMC5843 which is a 0.5mm pitch QFN. The steps are rather simple: - get a good PCB with the right footprint and soldermask - if you want to use solder paste, just apply an amount on the pcb and melt it with your solder iron. This should result in small dots of solder on the PCB. It's like a BGA, but with the balls mounted on the board. Working with solder paste but without stencil mask won't work for fine pitch applications. Just use normal solder wire for this task. It works equally well. - flux should not be necessary, but YMMV. - carefully place the QFN onto the solder drops. Make sure it aligns with the pads. Very small alignment errors will automatically be corrected during the reflow process. - place everything in your oven - recheck the alignment - heat the oven up until the solder melts. I used a piece of solder wire next to the board to see if the melting point was reached. - switch the oven off when you think it's done. The extra solder wire should look like a ball now and the chip should be sunken onto the surface of the PCB. Don't wait too long! That's it! good luck!

So the easiest solution was to combine what we have: a given Beagleboard and the Freerunner case. Other questions were what one could do with this. Here some ideas (not assuming it is complete - you may have more and it is a platform for your creativity): • experimenting with touchscreen and new user interfaces on Beagleboard • learn how the OMAP3530 CPU works • make it a truly open mobile application development platform by adding a battery pack and a UMTS usb stick • investigate how an Openmoko with UMTS and OMAP3530 feels (not from haptics but screen operation and UMTS speed) • porting SHR, QtMoko, Android, etc. to ARM-Cortex A8 And here some feature list: • PCB that fits into Freerunner case (top cover and middle part after cutting a hole) • works also without such a case (except speakers and earset) • Toppoly LCM interface (same display as used in the Freerunner - otherwise it would not fit into the case) • TSC2007 touch screen controller • Microphone • Earset and Speaker connector (for those sitting in the Freerunner case) • 2 buttons (AUX and Power) • 2 dual color LEDs (in the AUX and Power buttons) • vibracall driver • headset jack to connect microphone, earset and speaker For the software, we have to rearrange the code on our server a little and then it will be made public.

We would be happier if we could offer a motherboard replacement for the Freerunner. With OMAP and UMTS. But as Werner has already found out in the GTA02-core project this is still very far from becoming reality. The complexity is balancing circuit design with availability and cost of chips, and pcb layout with production processes. Nevertheless, the great open source mobile phone software developed by this community (SHR, QtMoko, FSO etc.) needs to have modern open and documented hardware to keep pace with pretededly-open platforms like iPhone, WebOS, etc. Therefore, this Openmoko Beagle Hybrid board gives us a tool to develop mobile applications with state of the art performance (except form factor). We, a small team of hardware developers, will continue to work on integrating everything better - but this is a long way to go. I am sure we will finally succeed because we have decided to do so, but I don't know when. So it is better to have something suboptimal than nothing... Nikolaus Michael There is now a new Wiki page for the project: http://wiki.openmoko.org/wiki/Openmoko_Beagle_Hybrid I have received some questions why we did not put all this into a nice design. The main reason is that we can't redesign the Beagleboard (it has fixed dimensions) and we can't afford to build plastic injection moulds (if someone has an idea how to reduce cost this is very welcome). So the easiest solution was to combine what we have: a given Beagleboard and the Freerunner case. Other questions were what one could do with this. Here some ideas (not assuming it is complete - you may have more and it is a platform for your creativity): • experimenting with touchscreen and new user interfaces on Beagleboard • learn how the OMAP3530 CPU works • make it a truly open mobile application development platform by adding a battery pack and a UMTS usb stick • investigate how an Openmoko with UMTS and OMAP3530 feels (not from haptics but screen operation and UMTS speed) • porting SHR, QtMoko, Android, etc. to ARM-Cortex A8 And here some feature list: • PCB that fits into Freerunner case (top cover and middle part after cutting a hole) • works also without such a case (except speakers and earset) • Toppoly LCM interface (same display as used in the Freerunner - otherwise it would not fit into the case) • TSC2007 touch screen controller • Microphone • Earset and Speaker connector (for those sitting in the Freerunner case) • 2 buttons (AUX and Power) • 2 dual color LEDs (in the AUX and Power buttons) • vibracall driver • headset jack to connect microphone, earset and speaker For the software, we have to rearrange the code on our server a little and then it will be made public.

We would be happier if we could offer a motherboard replacement for the Freerunner. With OMAP and UMTS.

What do you think? I don't know if there is enough room inside the case for a Gumstix. But generally, the Gumstix and Beagleboard are quite similar from circuitry. Maybe, the connectors (Video, USB-OTG, SD-Card, 2nd USB) are much different. We didn't because we simply had more experience with the BeagleBoard and it costs less.
