https://github.com/hallard/LoRa-E5-Breakout

Mainly based on LoRa-E5 mini board from Seedstudio, but since it was out of stock and I needed some specific wiring, I designed my own based on the Open Source design they made (thank for sharing)

I'm using mainly to flash custom firmware in it, and not using AT default firmware.

These boards have been received, assembled, and works as expected

• LoRa-E5 Module
• No USB/Serial, SMD FTDI 6 pins connector (use 3.3V FTDI One, not 5V)
• Exposed JTAG pins needed to flash module (PA13-SWDIO / PA14-SWCLK / RESET)
• Green Led on PB10
• Red Led on PB5
• Optional 2 Tactile Switch (boot and reset)
• 2 Antenna connector (u-Fl and SMA), select with 0 Ohm resistor
• I2C 4 pins location for "classic" sensors

Detailed Description

No specific documentation for now, it's just a kind of wiring helper as schematic.

I also assume that you are familiar with all LoRaWAN stuff, all setup/infrastructure/network server/provisionning and other are out of scope of this repository.

Firmware

Before flashing any custom firmware, I strongly advise to test the board with default AT-Firmware to get the keys (even if you can use your own of course).

Do do this, use 3.3V (and NOT 5V) FTDI USB/Serial adapter, I love this one from sparkun

• Connect FTDI on the 6 pins dedicated header of the breakout
• use them a terminal application and open the port on your computer corresponding to the FTDI device
• set terminal settings to 9600 bauds 8 bits no parity 1 stop bit (8N1)
• check with at command AT device should anwser +AT: OK
