$14+ Allwinner T113-S3 CPU module comes with 128MB RAM, 256MB NAND flash or 4GB eMMC flash

MYiR MYC-YT113X is a low-cost solderable CPU module powered by an Allwinner T113-S3 dual-core Cortex-A7 processor with 128MB on-chip DDR3 RAM, and fitted with either a 256MB NAND flash or a 4GB eMMC flash for storage.

The industrial temperature grade module provides a lower-end alternative to the company’s earlier MYC-YT507H Allwinner T507-H Cortex-A53 CPU module, and offers various display, camera, audio, Ethernet, USB, and low-speed I/Os through a 140-pin stamp hole design. It is designed for HMI, industrial automation, as well as display and control terminals.

- Optional 4G LTE/5G module via M.2 socket (USB) and two SIM card slots.
USB
- 2x USB 2.0 host ports
- 1x USB 2.0 OTG Type-C port
Serial ports – 1x Debug UART (TTL), 4x TTL serial ports
Expansion – 40-pin Raspberry Pi-compatible GPIO header with TWI, UART, etc.. and supporting MYIR’s MY-WIREDCOM RPI module to add CAN and RS232 interfaces
Misc – Power Switch, Reset button, user-programmable button
Power Supply – 12V/2A via DC jack
Dimensions – 110 x 90mm (4-layer PCB)
Temperature Range – -40 to 85 Celsius, but note the WiFi module is limited to -20 to 70 Celsius

MYiR provides a Linux BSP with kernel version 5.4.61, U-boot 2018.05, and the drivers for all peripherals, along with source code, and two root file systems, one minimal, one with a GUI. None of those is released publicly, so only customers would have access to it. There’s however some public code for other Allwinner T113-S3 hardware platforms, as we previously covered MangoPi MQ-Dual board and the 100ASK-T113-Pro development board, and its associated T113-S3 Core Lite CPU module.

The MYC-YT113S3-256N128D-110-I CPU module (256 NAND flash) is sold for $14, while the MYC-YT113S3-4E128D-110-I system-on-module with 4GB eMMC flash is offered for $17, while the respective development kits with all accessories (power supply, cables …) for $55 and $59. The optional MY-WIREDCOM for CAN Bus and RS485 adds $25, and the 7-inch touchscreen display is sold for $99. You’ll find the full details and purchase links on the product page.
