Under the hood

Want to know what’s inside the PLD? We had one of the developers step us through all the technical information inside the hardware.

Open device
based on Atmel™ ATmega328P μC, Arduino™ compatible design with 32 Kbytes of flash memory, and 2 Kbytes of SRAM
Additional 512 bytes of FRAM (high data reliability)
Pre-loaded with a switch test example using the PLDuino library
ISP programming through the Developer’s shield

Sensor connector: I²C, IRQ and switched power supply
Expansion slot: GPIO, ADC, Analog, I²C, SPI, UART and switched power supply
Debug: dedicated UART
