## Overview

An ESP32-C3 powered encoder controller with voltage level translator and CAN transciever.

* ESP32-C3

* 3-ch Voltage level translator using MOSFETs

* CAN bus transceiver

* RS232 transceiver

## Revisions

### 1.2

* Replaced XC6206 weak LDO with stronger AMS1117

* PCB antenna cutout for better RF performance

### 1.1

* Diodes between +5V and VUSB rails are removed.

* Added 2 x 100uF and 1 x 47uF capacitors to supply enough current when wifi starts up

### 1.0

* Initial release.
