Attention

Chipsee does not install a lithium battery by default, as we cannot ship products with batteries. We recommend you buy it locally and install it by yourself. The lithium battery part number is CR1220. Please Contact us if you need help.

Power Input¶

The EPC/PPC-CM3-101 industrial Pi PC can be powered by a wide range of input voltages: From 6V to 36V DC. There are two types of power input connectors. One is a 3 Pin, 3.81mm screw terminal connector, and the other is a 2.1mm DC input head. The polarity and the pinout is clearly marked on the housing of the CS12800RA101P version, as well as on the board itself of the CS12800RA101E version, as shown in the figures below.

../../../../../_images/Power6.jpeg — Figure 1020: *Power Input (embedded/enclosed version)*¶

Note that the “+” sign represents the positive power input, and it is printed both at the casing and as a silk-screen on the board of the embedded version. The “-” terminal is shorted to the ground.

Table 351 Power Connector¶
Power Input Definition
Pin Number	Definition	Description
Pin 1	Positive Input	DC Power Positive Terminal
Pin 2	Negative Input	DC Power Negative Terminal
Pin 3	Ground	Power System Ground

Note

The system ground “G” is connected to power negative “-” on board.
The central pin is positive.

Touch Screen¶

The EPC/PPC-CM3-101 industrial Pi PC uses a 5-point capacitive touch screen. The figure below shows the capacitive touch screen connected to the motherboard via the FPC connector.

../../../../../_images/TS_CON3.jpeg — Figure 1021: *Capacitive Touch Connector*¶

Attention

A capacitive touch screen is susceptible to power noise and Electromagnetic Radiation (EMR). It may cause LCD ripples or even capacitive touch malfunction. If using a capacitive multi-touch test application, you might notice the touch points float erratically across the display. There are several solutions to this problem:

Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.
Make sure that the EPC/PPC-CM3-101 Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.
Bad GND problem can also be confirmed by touching pin 3 of the Power Input connector with one hand while operating the capacitive touch screen with the other hand. In this case, the operator’s body acts as the Power System Ground.

Connectivity¶

There are many connectivity options available on the EPC/PPC-CM3-101 industrial Pi PC. It has 3 x USB 2.0 Host (can be customized to Host or OTG), 1 x Channel 100M LAN (RJ45) Ethernet connector supporting up to 1 Gbps, and 5 x UART terminals (RS232/RS485).

RS232/RS485/CAN¶

The serial communication interfaces (RS485, RS232, and CAN) are routed to a 16-pin 3.81mm terminal, as illustrated on the figure below.
