The PPC-J1900-236-C has several expansion connectors on the back side:
- three USB 2.0 connectors
- a USB 3.0 connector
- two LAN connectors
- four COM connectors (the four RS232 connectors by default; on top of which you can add COM1 and COM2 as optional RS485 connectors)
- an HDMI connector, and
- eight GPIO connectors
The WiFi module does not come with the product by default. It is an optional module and can be added when ordering.
A 4G/LTE module can be added to the product, but we do not currently offer it in our shop. We recommend you buy it locally, and install it yourself, as it’s quite easy to add.
The 16 Pin 3.81mm screw terminal connector includes 8 GPIO and 2 RS232.
