The Ebyte ECB31-PB is an Allwinner T113-S-based industrial SBC in the Raspberry Pi Model A form factor, and also supports CVBS(Composite Video Blanking and Sync) analog video interface used for FPV shooting, video capture card, and image systems for cars.
The Ebyte ECB31-PB is powered by an Allwinner T113-S processor with a dual-core Arm Cortex-A7 running up to 1.2GHz, a RISC-V core, and a HiFi4 DSP. It comes in two variants, the ECB31-PB1E8-I with 128MB DDR3 RAM using the T113-S3 SoC, and the ECB31-PB2E8-I with 256MB DDR3 RAM using the T113-S4 SoC. Storage includes 8GB eMMC flash and a Micro SD card slot. Networking features include Gigabit Ethernet, 2.4GHz/5GHz Wi-Fi, a mini PCIe slot for a 4G module, and a SIM card slot.
Display interfaces include a 4-lane MIPI-DSI supporting up to 1080p60 with touch, one CVBS output (NTSC/PAL), and two CVBS inputs (NTSC/PAL). Audio options provide headphone out (L/R) and microphone input. USB connectivity includes one Type-C port for power and programming, and two USB 2.0 Type-A host ports. For debugging, there is a UART header (2.54mm pin header).
Expansion is provided through a 40-pin Raspberry Pi 3A+ compatible GPIO header with I²C, SPI, UART, PWM, and GPIOs, as well as two CAN bus interfaces and an additional mini PCIe slot for a 4G module.
Other features include a reset button, power/operation/4G status LEDs, a 1.25mm RTC header supporting CR1220/CR2032 batteries, and on-chip watchdog support. Power is supplied through 5V/3A via USB Type-C, with 2x 5V and 2x 3.3V outputs available via the expansion header. The board operates from -40°C to 85°C with heatsink and airflow, and its dimensions are 65 x 56 mm, matching the Raspberry Pi Model A size.
In terms of software, the Ebyte ECB31-PB runs Linux 5.4 with support for U-Boot, Buildroot, and OpenWrt. The company provides full source code for the bootloader, kernel, drivers, and build system, along with cross-compilation tools and utilities for both Windows and Linux environments. Development tools such as PhoenixSuit and PhoenixCard are available for USB and SD card flashing, while documentation and resources, including the product manual, software development guide, user guide, and mechanical drawings, can be downloaded from the product’s page.
The Ebyte ECB31-PB industrial SBC with CVBS interface is available on AliExpress for $40.25 (128MB) and $44.39 (256MB), or from Ebyte’s store starting at $29.72.
