Connectors of the breakout boards fit to the pin blocks J2-J3-J4 on the SandGrain demo board. Demo board specifications can be bound in the SandGrain Demo Board Data Sheet v1.
Demo Board Data Sheet
Description
Demo Board for three SGT1001 token ICs (mounted on individual breakout boards) interacting with the CyberRock cloud platform.
Allows full system authentication evaluation of three ICs under the control of a Raspberry Pi. Three coloured LEDs for each IC breakout board indicate the authentication outcome. Interfacing uses the Pi-compatible 40-pin connector for easy interconnect using a flat cable.
A standard SPI mode0 interface and single 3.3V supply make it extremely easy to evaluate.
