Sensor.Engine MICRO Features
The Sensor.Engine MICRO (SEM) is a small programmable controller board meant to interface to sensors and control various modules. The SEM can be used in experimentation, learning, development, and implementation environments.
SEM Features:
A microchip 32 bit PIC processor (PIC32MX170F256B) loaded with a powerful Micromite MMBasic
A USB-to-PC connection for console (38400 baud) and potential firmware upgrades
Micro SD card socket for optional user-supplied micro SD card
.96" OLED display - 128 by 64
Three (red, yellow, green) push buttons
Power/function LED
3.3V on-board voltage regulator (250mA total - 50mA used by SEM - 200mA available)
RTC module support
Bluetooth and radio module console connection support
16 I/O lines
I/O features:
Digital inputs, optional pullup/down
