About the Sbc allwinner F1C200s PCB

Sbc allwinner F1C200s is an open source ESP32 PCB design by vd-rd, published on GitHub. It is a 4-layer board measuring 60 × 44 mm, with 105 components from 38 distinct parts.

Its main chip is the ESP32-S3-MINI-1U, from the ESP32 family. Other key parts include the MCP1640CH, AXP173, AP22811, F1C100s and PCA6408A. By type, the board carries 51 capacitors, 23 resistors, 10 diodes, 8 ICs, 5 connectors and 5 inductors.

It belongs with the iot & wireless designs in this gallery.

From the project

Open hardware board for Allwinner F1C100s/F1C200s processor with 32/64MB RAM, IO expansion and MicroSD storage

This board embeds a SIP (single core 533MHz ARM926EJ-S with 64MB DDR) with AXP173 PMIC, IO headers and microSD/eMMC storage. The board is also compatible with the smaller F1C100s that only embedds 32MB DDR RAM.

Note: The uC has two SDIO controllers (SDIO0 - 4bit wide, SDIO1 - 1bit wide). SDIO0 is used for SDCard. To provide wireless networking, while not sacrificing a large amount of pins, a design decision was made to use ESP32 module to provide WiFi/BT capabilities connected via SPI bus, leveraging ESPHOSTEDNG as a solution. ## Board overview (draft):

Sbc allwinner F1C200s: common questions

What microcontroller does the Sbc allwinner F1C200s use?

The Sbc allwinner F1C200s is built around the ESP32-S3-MINI-1U, from the ESP32 family.

How big is the Sbc allwinner F1C200s PCB?

The Sbc allwinner F1C200s measures 60 × 44 mm, has 4 copper layers and is 0.99 mm thick.

How many components are on the Sbc allwinner F1C200s?

105 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sbc allwinner F1C200s design files?

From the vd-rd/sbc_allwinner_F1C200s repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Sbc allwinner F1C200s design in my own project?

The repository has no license, so all rights stay with vd-rd. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sbc allwinner F1C200s without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
