The Neonode Prototyping Board is an Arduino-compatible microcontroller, based on the SAMD21 MCU. The board allows the user to directly connect a Neonode Touch Sensor Module (previously referred to as zForce AIR) through the onboard sensor port, with all 8 connector pads exposed. The prototyping board is only intended for development and prototyping. Meaning, it is not created to withstand challenging environments or demanding use-cases.
The prototyping board can also be configured using an Arduino development environment, for example the Arduino IDE. For easier configuration and implementation, include our zForce Arduino Library to your project.
