We worked with Stanford University to design the Hapkit Board, which supports the Hapkit open-source haptic device.
It merges a microcontroller Atmega328, Micro SD card Slot and Motor driver L298P, which can achieve these functions: control operation, data recording, motor driver. There are Hapkit-specific sensor connections: Mr Sensor connection and FSR Sensor connection. Standard Shield shape and Grove Interfaces, makes it convenient to connect more modules.
Its power can from Micro USB or 7v ~ 15v extern power. Only select extern power when you drive DC motors.
Working Voltage: 5V ~ 15V
Support SD Card Type: Micro SD card, FAT/FAT32 (less than 2G)
Max output current per channel: 2A
Output Duty Range: 0%~100%
You can develop a Hapkit using the Hapkit Board and following the instructions for building/purchasing the other hardware at http://hapkit.stanford.edu.
