About the Nissan-Leaf-Gen-3-Adapter-Board
Nissan-Leaf-Gen-3-Adapter-Board is an open source ESP32 PCB design by jrbe, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 131.6 × 104.1 mm, with 72 components from 33 distinct parts.
Its main chip is the ESP32-S2-WROOM, from the ESP32 family. Other key parts include the -, AP1117-33 and TPS22810DBVR. By type, the board carries 16 capacitors, 15 resistors, 12 diodes, 5 transistors, 4 ICs and 2 connectors.
From the project
Gen. 3 Nissan Leaf Inverter Open Inverter Mini Mainboard Adapter PC Board
This is a work in progress, V0.0.4 is current but is not a production release yet. Johu (Open Inverter) could not get a motor spinning in closed loop control. There are also many board settings to work out still.
The Wiki for this board is here, https://openinverter.org/wiki/NissanLeafGen3(2018upEM57)
There are many options built into this board. Multi-footprints for the 2 main connectors for SMD and through hole options, E-stop bypass or use, auxiliary outputs with different voltages, etc. See the wiki above for details.
