Project Status
ProtoJS is small (5x5cm) board with a minimal S08JS implementation and a standard 100mil prototyping area. While similar in features to our microJS, protoJS is more suited to permanently wire simple one off USB projects.
Features
- support S08JS8 and S08JS16 in SO-20W package
- support 3.3V and 5V I/O (stuff option)
- mini USB connector
- BDM connector (for programming/debugging)
- All port pins routed to the headers
- 2 LEDs (1 power, 1 controlled by PTB0)
