SIGPwny's [[guides/fallctf-2025/badge/index|Fall CTF 2025 badge]] for the first time featured a fully custom board and comes with an [ESP32-S2-SOLO-2](https://www.espressif.com/sites/default/files/documentation/esp32-s2-solo-2_esp32-s2-solo-2u_datasheet_en.pdf) microcontroller. (Previous badges simply used a [Raspberry Pi Pico](https://www.raspberrypi.com/products/raspberry-pi-pico/), which featured the [RP2040](https://www.raspberrypi.com/products/rp2040/) microcontroller.)

During Fall CTF 2025, badges were distributed with FreeRTOS, running [MicroPython](https://micropython.org/) as a task to execute the programs built for Fall CTF. This was done to make the badge easily hackable, as editing Python code is simple and does not require a build process since MicroPython is a runtime and interprets Python code on the fly.
