Multi-Interface Communication Hub
A board with a wide range of applications that allows you to communicate and interact with low and high voltage (3.3V-24V) devices safely, through USB-C, USB-A, I²C, RS485, CANBUS and UART. It also has 8 GPIO pins and 5V power output. The upstreaming-facing USB-C port is isolated to protect the connected controller from high voltage spike.

8-Channel ADC Shield
An extension board for a RS485 8-channel high-frequency ADC. It can transmit converted ADC data through USB-C with sample rate of over 1MS/s. It uses 6.35mm TRS Jack for analog signal input (because headphone cables are good insulating cables).
Specifications
Interfaces:
1 x Molex Micro-Fit 2-Pin Connector for 24V power input
1 x USB-C upstream-facing port
8 x 6.35mm TRS Jack Connector for analog input
1 x JST PH 2-Pin Connector for RS485 direct read
Features:
UMW® SP3485E RS-485/RS-422 transceiver
Silicon Labs® USBXpress™ CP2102N USB to UART bridge controller
