Zwölf is an open microcontroller platform for simple embedded applications that require long-term data retention and/or long-term functionality.
Zwölf modules are available in a versatile package that can be soldered surface mount, through-hole (DIP-12) or used as a removable module with a DIP socket or spring contacts. The modules are also compatible with 6-pin PMOD sockets.
While the modules are built with a variety of MCUs, FPGAs and memories from various vendors, each module is partially pin-compatible and implements the same code-compatible stack-based CPU and a common interface for control and programming.
Zwölf is still under development, for more information please contact us or join the discussion on our BBS.
Tools
- Spielplatz is a evaluation/development board.
- Wolfsjunge is a minimal controller/programmer.
- Wolfshöhle is a minimal breakout/host board with 16 digital GPIOs.
