Ah yes, that backbench… Been looking at Osh Park for some shared projects but no dice.
It would be nice to have some design with power (battery clip, usb, LDO), ESP32 footprint, RFM footprint and perhaps some meander and/or uFL for the LoRa antenna. Some GPIOs exposed. Breakout is nice, but when it’s an all-in-one I won’t be needing the breadboard.
I’m lacking the skills on KiCad, but I have some PCB design at work on the ESP32 without the LoRa part. I’ll ask the schematics designer if he’s willing to contribute to the community.
Completely missed this LoPy, but some E30 is not hitting the sweet spot for me by a long shot,
So I’m I able to work in C/C++ on the IDF and skipping Python as I can flash my own IDF code as we do now? As a development board this could be interesting.
I’m looking at https://github.com/berkutta/esp32_lmic with some interest, but could be we will be sponsoring a port throughout the summer as we are moving away from PIC to ESP32 with one particular solution we currently use on a B2B application.
So I’ve been working with the WiPy and LoPy boards for some months now. I’ve done some LoRaWAN experiments in MicroPython which are nice. I also flashed the WiPy boards with my own pure C/C++ IDF projects which give me more flexibility running tasks and connectivity (I use AWS IoT a lot when running over WiFi).
I’m still looking for a pure ESP32 LMIC IDF port. Came across the Lua-RTOS-ESP32 project which has an IDF port at first glance.
But before diving in. Are we still short of an ESP32 IDF port of the LMIC stack?
Assembled, mounted, plugged onto Lolin32 tested, first TTN join this night
just a little error RST line of RFM95 connected to GPIO35 which is input only (sad) so you can’t reset RFM by software but do you really need it? If you really need it, quick fix add wire between between GPIO33 (unused) and GPIO35 and reset using GPIO33
I need to clean up and publish to github, in the meantime you can order them on PCBs.io, have fun
Reset fixed in V1.1 PCBs.io it’s now on GPIO25
