EPC35 Baseboard Hardware Manual - Baseboard Concept


Baseboard Concept

All information in the next chapters is applicable to LAY0962B, HW06/14 PCB version of the

EPC35 baseboard.

The EPC35 baseboard is a cost-efficient and high reliable baseboard developed for using with

EPC35 CPU module based on Texas Instruments AM335x Cortex-A8 SoC.

Primary the EPC35 baseboard is designed for evaluation, testing and prototyping of EPC35 CPU

module enabling quick and easy start-up of customer projects.

The EPC35 baseboard has the most used interfaces like RS232, USB Host, Ethernet, CAN, RTC

over IIC interface, RGB interface and Backlight unit for TFT Displays up to 7”. The extension

connectors make it possible to create own add-on boards like WLAN, Bluetooth, GSM and so on

to support fast prototyping and software evaluation. Customers may use the EPC35 baseboard

schematics or part of them to create their own baseboard to reduce time-to-market and to

save costs of their designs.

The EPC35 baseboard uses Q7 MXM 230 pin as mating connector and has a form of 100 mm x

120 mm.

Analog Inputs AIN0 to AIN4 can be optional changed via resistor array on the left side of X301

to adapt the signals from touch to suitable AIN’s for different 4-wire touch screens. The

resistors are places pad on pad for each AIN signal to avoid incorrect configuration.
