Why are we releasing this as a pre-release before publishing next week?
This is a special release for those using ESP32-Sx devices with WipperSnapper. We’ve updated WipperSnapper to be built off the absolute latest version of the Arduino ESP32 core -V3.0. However, the official Arduino ESP32 version 3.0.0 is currently an alpha and includes potentially breaking changes.
We’d like to get this into the hands of people who actively use WipperSnapper and want the absolute latest firmware version. Internally, our WipperSnapper team will also be using this pre-release for their projects and builds.
What does this include?
For ESP32-x devices, WipperSnapper is now based on ESP-IDF v5.1 (release notes). At the time of writing, Espressif has released two versions of the Arduino ESP32 Core alpha v3.0.0 – alpha 1 and alpha 2. We’ve migrated our firmware to match the core API changes and updates for these alpha releases.
Breaking Changes in Alpha
Adafruit FunHouse ESP32-S2: The process for installing Alpha 74 on the FunHouse is different than the other boards since we’ve made the partition for WipperSnapper larger, and removed a partition for an OTA binary in the process. The installation is currently for advanced users only. It will be the usual drag/drop install process for the beta release.
You will need to install the latest arduino-esp32 core from GitHub. In Arduino IDE, select “TinyUF2 No OTA” in the partition scheme menu and upload any sketch to the FunHouse.
Then, drag and drop the alpha 74 UF2 file to the HOUSEBOOT volume

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
