Luckfox Pico Mini is a tiny (28 x 21 mm) board based on the Rockchip RV1103 Cortex-A7 camera SoC with a built-in 0.5 TOPS NPU, 64MB on-chip DDR2 RAM, USB-C port for power and data, two rows of headers with up to seventeen GPIOs, and five castellated holes for Ethernet.
Two versions are offered: the Pico Mini A with a microSD card slot or the Pico Mini B with an extra 128MB SPI NAND flash. Both boards are a shorter version of the Luckfox Pico with similar features but additional GPIOs and the Luckfox Pico Plus model also adds an RJ45 Ethernet port.
Luckfox Pico Mini A and B specifications:
- SoC – Rockchip RV1103 SoC
- CPU – Arm Cortex-A7 processor @ 1.2GHz + RISC-V core
- Memory – 64MB DDR2
- NPU – 0.5 TOPS NPU with support for INT4, INT8, and INT16
- ISP – 4M @ 30 fps ISP
- Storage
- MicroSD card slot
- Luckfox Pico Mini B only – 1Gbit (128MB) SPI NAND flash (W25N01GV)
- Camera – 2-lane MIPI CSI connector

- 2x 11-pin headers and castellated holes with up to 17x GPIOs, 14x PWM, 4x UART, 1x SPI, 1x I2C, 2x ADC, 5V (VBUS), 3.3V out, 1.8V out, and GND
- 5x castellated holes for Ethernet
- Misc
- BOOT button
- Act and user LEDs
- Power Supply – 5V via USB-C port
- Dimensions – 28.14 x 21.00 mm
All Rockchip RV1103/RV1106 Pico boards from Luckfox run the same lightweight version of Linux with Busybox that boots from a microSD card or the SPI flash. LuckFox provides instructions to get started, links to the images, PDF schematics, and additional information on the wiki. An SDK is provided that works with Ubuntu 22.04, but other versions of Ubuntu are supported through Docker.
You’ll need a USB Type-A to Type-C cable and A USB to UART debug board to get started, and most people will likely want to get the 3MP camera module based on the SmartSens SC3336 CMOS camera sensor.
Luckfox Pico Mini A and B boards are sold on AliExpress for $10.25 to $14.39 depending on the model and whether soldered GPIO headers are needed. You’ll also find all variants on Amazon with a small markup. The SC3336 3MP camera module can be purchased separately on Aliexpress for under $10 or Amazon for about $16. If 64MB DDR2 is not quite enough for your project, you’ll need one of the RV1106 boards with 128MB RAM such as the Luckfox Pico Ultra or LuckFox Pico Pro/Pico Max.
