Hardware part of the OpenHT - an open-source, SDR handheld transceiver.
Description
The device is a complete, low RF power I/Q transceiver, capable of supporting virtually any mode (including M17 and FreeDV). It is built around the AT86RF215 chip by Microchip/Atmel and LIFCL-40-9SG72C FPGA from Lattice as a shield for 32F469IDISCOVERY. It is possible to use the board with other MCU platforms.
Technical details:
- frequency range: 389.5 - 480, 2400 - 2483.5 MHz (RX, TX frequency range is limited by your local laws)
- RF power output: <14dBm (<25mW)
Assembly tips and U204 issue
After the board has been populated, perform the steps below:
- Remove JP201 (undervoltage lock-out).
- Remove U204 (you need to take the lower shield off).
- Using a copper wire, connect
VINandVBAT. - Secure goldpin headers in place by putting them on the DISCO board (Arduino male connector and the 2x8 female connector) and solder them.
- Populate JP401 and short the two left pins,
JTAG_ENtoGND, "OFF" position. - Prepare a micro-SD card with the FPGA image, its filename should be
OpenHT_impl_1.bit. The SD card has to be preformatted with FAT32. - Plug the mini-USB port and flash the firmware from the
mainbranch. - In the GUI, tap on the cog icon (upper left corner), then press the
Erase NORbutton. After a few seconds (about 3), press theSD to NORbutton and wait a few seconds more. - After the flashing is done, press and hold the power-on button for at least 1.5 seconds. The "LED" next to the cog icon should light up in green.
Step 8) needs to be performed only once for a fresh FPGA image. After that, the image is transferred to the NOR flash and is supposed to be retrieved by the FPGA automagically. It is highly recommended to use terminal for getting debug info. The terminal is 115,200 baud, 8n1, over the COM port exposed by the DISCO board.

Questions
How big is the OpenHT RF PCB?
It measures 60 × 127 mm and has 4 copper layers, 1.64 mm thick.
What parts does the OpenHT RF use?
199 parts, built around the LIFCL-40-9SG72C, AT86RF215-ZU, LFCN-2500+ and LFCN-490+. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the OpenHT RF KiCad files?
From the M17-Project/OpenHT-hw repository on GitHub, at the commit this page was made from: the board is OpenHT-RF/OpenHT-RF.kicad_pcb and its schematic OpenHT-RF/OpenHT-RF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenHT RF design in my own project?
Its repository states no licence, so its author keeps all rights: ask M17-Project before reusing the design.
