MYIR Launches a Tiny Yet Feature-Packed $19 SOM Built Around STMicro's New STM32MP135 Chip
Designed for a small footprint, this surface-mount SOM offers up to 4GB of storage and 512MB of RAM — with pricing starting at $19.
Shenzhen-based embedded electronics firm Make Your Idea Real (MYIR) has announced the launch of a low-cost system-on-module (SOM) built around STMicroelectronics' STM32MP135 chip, with the promise of Linux compatibility and support for up to 108 general-purpose input/output (GPIO) pins: the MYC-YF13X.
"The [MYC-YF13X] features a dedicated LCD-TFT parallel display interface, a 16-bit parallel camera [interface], and dual Ethernet ports, and is particularly suitable for applications such as entry-level industrial human-machine interfaces (HMI) and embedded devices for energy and power management," MYIR says of its creation. "In additional to the STM32MP135 processor, the MYC-YF13X module has integrated DDR3L, external memory and carried out a variety of peripheral and IO signals through the 1.0mm pitch 148-pin stamp-hole (castellated-hole) expansion interface."
The chip at the heart of the compact SOM is STMicro's STM32MP135, a member of the STM32MP13 range it launched back in March. Featuring a single Arm Cortex-A7 processing core running at up to 1GHz, the chip retains the twin Ethernet ports of the mid-range STM32MP133 while also offering display and camera interfaces — while boasting twice the Ethernet ports of the entry-level STM32MP131.
MYIR has placed this chip on a compact surface-mount module measuring just 39×37mm (around 1.53×1.46") with a either 256MB or 512MB of DDR3L, a choice of 256MB of NAND flash or 4GB of eMMC storage, and a 32kB EEPROM, all rated for an industrial-grade operating temperature range of -40 to 85𝆩C (-40 to 185𝆩F).
The module's 148-pin package includes connectivity for the two Ethernet ports, two USB 2.0 ports, and buses including two SCI, two CAN FD, four I2S, and five I2C, along with the promised 16-bit parallel camera interface and color LCD interface. There are also two Serial Audio Interfaces (SAIs) and up to 108 general-purpose input/output pins, including two analog to digital converters (ADCs).
To get users started, the company has also designed a carrier: The MYD-YF13X Development Board. "It has a versatile base board to facilitate the expansion from the MYC-YF13X through the 1.0mm pitch 148-pin stamp-hole interface," MYIR says, "[and] a rich set of peripherals and interfaces have been brought out such as RS232, RS485, two USB 2.0 HOST and one USB 2.0 OTG [On-The-Go], two Gigabit Ethernet, CAN, one microSD card slot, one USB based mini-PCIe 4G module interface with one SIM card holder, LCD interface, camera interface, audio input and output as well as two extension headers."
The company is now accepting orders for the board, with pricing starting at $19 for the 256MB RAM and 256MB flash variant of the board, or $69 for the development board bundle with the same hardware. More information is available on the MYIR website.
