modtronix H
Terminal for sending and receiving data via Semtech SX1276 chip. It uses the FRDM-KL25Z board, with a Modtronix inAir9 SX1276 board, and Modtronix SHD3I shield. The inAir9 module is mounted in iMod port 3 of the SHD3I module. The SHD3I shield is mounted on the FRDM-KL25Z board.
Dependencies: SX127x_modtronix mbed
