Nuvoton NuMicro MA35D1-powered industrial SoM and dev board features dual GbE ports, cellular connectivity, and more

MYIR has recently introduced MYC-LMA35 industrial SoM and its associated development board built around the Nuvoton NuMicro MA35D1 microprocessor with two Arm Cortex-A35 cores and one Arm Cortex-M4 real-time core for processing. The SoM comes in a BGA package with connectivity options such as dual Gigabit Ethernet, cellular connectivity, Wi-Fi/Bluetooth, and various other interfaces like RS232, RS485, USB, CAN, ADC, GPIO, and more. All these features make this SoM and its associated dev board useful for demanding edge IIoT applications like industrial automation, energy management systems, smart city infrastructure, and remote monitoring solutions.

Previously we have seen MYIR introduce various SoM and development boards like the MYC-LR3568 Edge AI SoM, and the MYC-YF13X SoM and we have also written about similar industrial dev boards such as the Firefly ROC-RK3576-PC, the Nuvoton NuMicro M2L31 development board, and many more. Feel free to check those out if you are interested in the topic.

It’s been more than a year and they are yet to start selling the IC directly on Nuvoton store (which is half the reason for choosing them).

Contacted them about it and they have it strictly behind a sales/quote wall, so no easy access for prototypers.
