Those two pins are just general GPIOs, not a serial port, so getting data into them would be a bit tricky unless you were willing to bit-bang I2C or SPI. > I am interested in a radio link > for my own electronics projects, but the RF part doesn't really interest > me.

TeleMini doesn't have the wires necessary -- the board is just too small. Both TeleMetrum and TeleDongle have a SPI interface available. There's even support for companion boards in the default TeleMetrum firmware. So, if you need companion port support *and* ejection control, you can use TeleMetrum. If you just need an RF link, you could fly a TeleDongle, if you were willing to bodge the power connection together. TeleMini is just too tiny to have the necessary connectors though. -keith _______________________________________________ altusmetrum mailing list altusmetrum@lists.gag.com http://lists.gag.com/mailman/listinfo/altusmetrum
