I enjoy seeing modules that can make designing other devices easier, and when I did a call for design reviews, [enp6s0] has submitted one such board to us. It’s a module called TinySparrow (GitHub), that helps you build your own vehicle ECUs and any other CAN-enabled things. With a microcontroller, plenty of GPIOs, a linear regulator and a CAN transceiver already onboard, this board has more than enough kick for anyone in hobbyist-range automotive space – and it’s surprisingly tiny!
