Pmod crypto
About the Pmod crypto PCB
Pmod crypto is an open source PCB design by fm4dd, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 41 × 20.3 mm, with 11 components from 8 distinct parts.
Other key parts include the ATECC508A. By type, the board carries 3 capacitors, 2 connectors, 2 test points, 2 resistors, 1 IC and 1 switch.
From the project
1Mbit I2C CRYPTO AUTH PMOD ATECC508A
This PMOD connects the Microchip ATECC508A crypto authentication device over I2C, using Digilent's PMOD interface type 6A per PMOD specification v1.3.1. The PMOD module can be chained to add additional I2C devices to the bus. The onboard I2C bus pull-up resistors can be enabled/disabled, using the DIP switch.
This design is registered under the OSHWA Open Source Hardware Self-Certification:
