Module17
Module17 is an open source STM32 PCB design by M17-Project: a 4-layer, 100 × 83 mm board with 186 components (79 distinct parts). It is built around the LM4991MA/NOPB, STM32F405RGT6V, TPS7A2033PDBVR, TP6841S6 and more. Filed under audio and rf & radio.
M17 modem board for 9600-baud capable radios
This project provides a standalone modem that transforms any 9600 baud capable transceiver into an M17 compatible radio. It is based on a STM32F4 microcontroller and is designed to run the OpenRTX firmware. Audio and PTT connectivity is given through a "Kenwood 2 Pin" compatible connector (2.5 and 3.5mm audio jacks) or an OHIS connector (this is NOT an internet connector). Power supply of 6 to 15 volts can be applied through a 5.5/2.5mm DC plug.
