Our recently concluded event in Europe saw the return of the Hackaday Communicator badge — a stylish handheld gadget with a QWERTY keyboard, a LoRa radio, and an ESP32. It came complete with a simple messaging app built into it’s MicroPython firmware, and by all accounts it was a great success.
But there was certainly room for improvement, which is where [Giovi321]’s new firmware for the badge comes in. It brings support for Meshtastic proper, as well as longer battery life support for GPS module. To install this firmware you will need to have the ESP-IDF but fortunately there are very comprehensive instructions provided to help you. Under the hood it’s running FreeRTOS.
It’s something which is so often missing with an event badge, any sense of how it might have a life after the event rather than becoming a piece of e-waste. The Communicator badge is such a nice physical design that it obviously has potential, so this firmware unlocks it and gives the badge a use out in the real world. We really like it for this, and we’ll be flashing a few of our badges over to give it a shot shorlty.
If you’re looking to upgrade the hardware on your Communicator, check out the custom RGB keyboard we covered last week.
