High-performance AM335x SoM supporting WiFi/Bluetooth module

AM335x SoM

What it is?

The MYC-C335X-GW CPU Module / SoM is a newly-released product by MYIR, It is powered by TI’s AM335x ARM Cortex-A8 Processor (using TI am3354 on board by default), which are capable of running at Up to 1GHz.

The SoM has a very compact size measuring only 50mm by 40mm, with configurations onboard including 256/512MB DDR3L, 256MB Nand Flash/4GB eMMC, 256Kbit EEPROM, a Power Management IC (TPS65217C), on the back of the SoM, it has two 0.8mm pitch 80-pin Board-to-Board Expansion Connectors, which bring out multiple signals.

The SoM runs Linux 4.14.67, capable of running in -40 to +85 Celsius extended temperature operation. Benefiting from the features (PowerVR™ SGX530 for 2D and 3D graphics acceleration) of the TI AM335x processors, the MYC-C335X-GW is an ideal solution for industrial gate-way, high-end HMI and other embedded applications.
