Refining the UCMOD architecture by defining a clearer boundary between microcontroller modules and carrier boards.

Testing the PICkit 5 with the UCMOD-0, moving from Arduino to plain C with MPLAB, and disappearing down a couple of 8-bit microcontroller rabbit holes.

Pruning the Protoworks development pipeline, introducing a clearer naming scheme for UCMOD modules, and starting work on a lightweight JWT authentication API.

Further development of the STM32G0-based UCMOD-1, adding OLED and Qwiic connections while defining standard small and large UCMOD module form factors.

Defining a standard auxiliary connector for UCMOD microcontroller modules, providing additional peripheral interfaces and microcontroller-specific GPIO.

Software testing the ATtiny1614-based UCMOD-0, configuring its clock and brown-out detection, measuring RS485 bus voltages and sending data to a Raspberry Pi Pico.

Programming and performing the first software tests on the ATtiny1614-based UCMOD-0 using Arduino, megaTinyCore and an UPDI Friend.

A visit to Farset Labs’ Maker Night in Belfast, followed by progress on the STM32G0-based UCMOD-1 microcontroller module.

Testing the Rev C Isolated RS485 Building Block Board and the first ATtiny1614-based UCMOD-0 microcontroller module.

A small revision to the ATtiny1614 UCMOD-0 module, adding UPDI power isolation and a connector layout compatible with the Adafruit UPDI Friend.
