From: Bastian Germann <bage@xxxxxxxxxxxxx> The Testbox board is an open hardware enhancement for the Lamobo R1 router board. The Testbox board is used in the CI-RT project to manage devices under test (https://ci-rt.linutronix.de). The hardware project is located at https://github.com/ci-rt/testbox-shield The Testbox v2 expands the Lamobo R1 router board with - a power supply, - a CAN bus PHY, - a power control, - a relay, - an I2C EEPROM, - a secure key storage (ATECC608a) and - two RS232 compliant serial ports.
