Hey Trevor,

I sent messages to the announce group last Tuesday and again yesterday

Aliexpresss is full of confusing pages.  Some intentionally so.

The Lichee RV is a slightly confusing product too.  This might be helpful:
  


- the processor board has a double M.2 connector, like a pair of NVMe 
  drives.  Both must be connected to something.

  It also has:
a TF card slot (think SD card).
a USB C OTG socket.
an SPI socket to connect a 1.14" LCD

- the "dock" (AKA "bottom board") has a pair of M.2 sockets for the 
  processor board.
  It has most of the things you would hook up.

Most pages have a selector box for "color" which is often not colour
at all.  In this case, the selection box is "bundle:".

If you click one of the boxes under "bundle:", you will be making a
selection.  To the right of "Bundle:", in grey letters, you will see
the name of that selection.  And you will see the price change.

If you click to the selection with C$53.35 price, you will see a
description "with wifi 1G".

Some of the bundle selections are not at all clear.  For example, the 
C$10.98 bundle says "with wifi 512M".  What could it be?  It is too cheap 
to include everything; the picture shows the dock; I presume that it is 
not a bundle and does not include the processor board.  But then why does 
it say "512m" when the memory is on the processor board?

There are many other listings that you can find on AliExpress.com if you 
search for Lichee RV.  I haven't looked for the cheapest (too much work) 
or the best (how would you be able to tell?).

Like I said, confusing.

Warning: if you search AliExpress, you will see links to listings with
low prices.  These prices are the lowest of all the "color" selections
and often are not what the "headline" says it is.

Re: [GTALUG] RISC-V

[D. Hugh Redelmeier via talk]

| From: Stewart C. Russell via talk 

| The only RISC-V I have is a WEMOS D1 Mini C3 —
| 
https://universal-solder.ca/product/wemos-d1-mini-c3-v1-0-0-esp32-c3fh4-genuine-lolin/

This is based on an ESP32-C3 which has a single 32-bit RISC-V core.
  

You may have others RISC V things about, for example embeded in disk drives.

You can get a RISC-V that runs some kind of linux for not too much
money.  The Sipeed Lichee RV has an Allwinner D1 which uses the
XuanTie C906 RISC-V 64-bit core.  Inexpensive but not very powerful.

You can buy these from AliExpress.com.  I don't quite understand the bits.  
You seem to have to buy the processor and a "dock".  Most units have 512M 
of RAM but some have 1G.

For example, on this page, if you pick the $53.35 "bundle", I think you 
get a complete system with WiFi and 1G of RAM.  11.76 shipping.  But I'm 
not sure because the description is poor.  Still, it is useful just to see 
the brochure (just duplicated from SiPEED, I presume).
