Image of Board

BPI-Pico-S3 is the same size as Raspberry Pi Pico board, equipped with ESP32S3 chip, 8M flash, 4-layer PCB, electroplated half-hole process, ceramic antenna, supports 2.4 GHz Wi-Fi and Bluetooth® LE dual-mode wireless communication, is a development board designed for IoT development and Maker DIY.

Features:

  • ESP32-S3R2: Xtensa® dual-core 32-bit LX7 microprocessor, up to 240 MHz; 2.4G Wi-Fi + Bluetooth LE; RISC-V Ultra Low Power Co-processor; 2 MB Quad SPI PSRAM is integrated in the package, so don’t worry too much about using massive buffers, it’s basically sufficient.
  • 8MB Quad SPI Flash
  • Pins and Pads: It’s the same size as Raspberry Pi Pico board, can also have headers soldered in for use in a breadboard or perfboard, or can be soldered directly onto a PCB with the castellated pads. There’s 20 pads on each side, with groups of general purpose input-and-output (GPIO) pins interleaved with plenty of ground pins.
  • Order of Pins: Keep the same order as Raspberry Pi Pico board in circuitpython. You get a total of 27 GPIO pins, 4 of those can be analog inputs.The ADC_VREF on Raspberry Pi Pico was change to GP29_A3 on BPI-PicoW-S3. In fact, the pin function assignments of ESP32S3 and RP2040 chip are not exactly the same, so redefine the pin order in circuitpython to adapt.
  • Native USB Port: ESP32-S3 full-speed USB OTG interface, using microUSB Connector with back-feed protection. The interface is used for power supply to the board, for flashing applications to the chip, for communication with the chip using USB protocols, as well as for JTAG debugging.
  • 5V to 3.3V DC/DC: Maximum theoretical output 2A 3.3V.
  • Reset Button: Support double-clicking the reset button to enter the UF2 bootloader.
  • BOOT0: If the UF2 Bootloader is removed, you can use any conductor bar such as metal pins or tweezers to short it to put the EPS32S3 chip into bootloader mode, then the UF2 Bootloader can be re-installed.
    • Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.
    • Short circuit BOOT0 contact.
    • Press and release the Reset button.
    • Release the BOOT0 contact.
  • RGB LED: Addressable WS2812 RGB LED, control it with board.NEOPIXEL in circuitpython.
  • Monochrome LED: Control it with board.GP25 or board.LED in circuitpython.

CircuitPython 8.0.0-beta.4

This is the latest unstable release of CircuitPython that will work with the BPI-PicoW-S3.

Unstable builds have the latest features but are more likely to have critical bugs.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.

Install, Repair, or Update UF2 Bootloader

Latest version: 0.11.0

The UF2 bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. If a UF2 bootloader is installed, you can check its version by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FTHRS2BOOT, MAGTAGBOOT, HOUSEBOOT, etc.)

It is not necessary to reinstall a UF2 bootloader you unless a BOOT drive is not visible when in UF2 bootloader mode, or you know of a problem with your current UF2 bootloader.

If a UF2 bootloader has never been installed on the board, or the UF2 bootloader was removed by erasing or overwriting the flash, the UF2 bootloader must be installed in order to flash .uf2 files onto the board. .bin files can be uploaded without a UF2 bootloader, using the ESP Web Flasher or esptool.py.

Note: update.uf2 files are not currently working on ESP32-S2 or ESP32-S3 boards.

Important: this will erase previously flashed firmware and sketches from the board, but needs to be perfomed only once.

The instructions here are general. We recommend you consult the manufacturer's board documentation for detailed instructions, which may be different.

  • Unzip to find the file combined.bin.
  • Place board in bootloader mode:
    • Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.
    • Press and hold down the BOOT or 0 button.
    • Press and release the RESET or RST button.
    • Release the BOOT button.
  • Upload combined.bin (Google Chrome 89 or newer):
    • Open ESP Web Flasher in a new window/tab.
    • Select 460800 Baud from the pull-down menu (top-right).
    • Click Connect (top-right).
    • Select the COM or Serial port from the pop-up window.
    • After successful connection, click Erase.
    • After successful erase, click any Choose a file..., then locate and select the combined.bin file unzipped earlier.
    • After successfully choosing combined.bin, click Program.
    • After the TinyUF2 firmware update is complete, press the RESET button on the board. A new drive BOOT should be visible in your file browser.

After installing the UF2 bootloader, enter the bootloader by double-clicking the reset button. On boards with an RGB status LED, tap reset once, wait for the LED to turn purple, and tap again before the purple goes away. On other boards, consult the board documentation.

After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to load or reload CircuitPython using the .uf2 file.
