Further development of the STM32G0-based UCMOD-1, adding OLED and Qwiic connections while defining standard small and large UCMOD module form factors.
Building a Simple Workshop Inventory System
Starting work on a simple QR-code-based inventory system for tracking tools, equipment and materials across workshops and other physical locations.
Defining the UCMOD Auxiliary Connector
Defining a standard auxiliary connector for UCMOD microcontroller modules, providing additional peripheral interfaces and microcontroller-specific GPIO.
Software Testing the UCMOD-0 over RS485
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 Testing the UCMOD-0 with Arduino and UPDI
Programming and performing the first software tests on the ATtiny1614-based UCMOD-0 using Arduino, megaTinyCore and an UPDI Friend.
Maker Night and Designing the UCMOD-1
A visit to Farset Labs’ Maker Night in Belfast, followed by progress on the STM32G0-based UCMOD-1 microcontroller module.
First Hardware Tests of the UCMOD-0 and RS485 Rev C

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