First version sold at hatlabs.fi.
Changes to 0.3.1:
- Move bypass capacitors further away from the mounting holes
- Fix the erroneous solder jumper silkscreens for GPIOs 1 and 3
- Improve the silkscreen for the 2x3 power connector header
- Change some components according to component availability
Changes to 1.0.0:
- Change the power input buck converter to XL1509 for easier part availability
- Instead of the ISO1050 isolated CAN transceiver, use a separate digital isolator and transceiver
- Use Phoenix MC type 3.81 mm pluggable screw terminals for power input and CAN bus connectors. These connectors are mechanically more durable and easier to use than the JST XH type connectors used earlier.
- Connectors and headers are now pre-soldered to the board
Changes to 2.0.1:
- Minor part changes to improve part availability
