About the CAN4VSCP Frankfurt Eth. PCB

CAN4VSCP Frankfurt Eth. is an open source ESP32 PCB design by grodansparadis, published on GitHub under the CERN-OHL-1.2 license. It is a 4-layer board measuring 42.1 × 72 mm, with 71 components from 43 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the LAN8720A, SN65HVD232 and R-78B3.3-2.0. By type, the board carries 28 resistors, 15 capacitors, 13 diodes, 4 ICs, 4 connectors and 4 switches.

It belongs with the iot & wireless designs in this gallery.

From the project

Frankfurt Ethernet to CAN4VSCP bridge

This work is based on original work done here.

Frankfurt Eth is a tcp/ip and MQTT CAN4VSCP gateway. The module is available in two versions. One without PoE and and one with PoE.

The module is plug and play. Just connect to a CAN4VSCP system and go to work. You can connect to the module using VSCP tcp/ip link protocol or set it up to talk to a MQTT broker of choice.
