ESP32-DIV v2 — Field Manual

CHAPTER 01 · OVERVIEW

Meet the ESP32-DIV v2

The ESP32-DIV v2 is a two-board handheld built around the ESP32-S3, a bright 2.8″ touchscreen, and a modular RF shield that stacks 3× NRF24L01, a CC1101 sub-GHz transceiver, an IR front-end, and optional RFID/NFC (PN532) and GPS modules. It is the "Swiss army knife" for wireless research — but designed from the ground up as an open, hackable alternative to closed multi-tools.

// WHO IT'S FOR

Security researchers, RF hobbyists, CTF players, and firmware tinkerers who want a transparent, MIT-licensed platform they can extend in the Arduino/PlatformIO toolchain.

What's new in v2

ESP32-S3 replaces the classic ESP32 — fixes pin conflicts, better USB support, room to grow.
Two-board stack with pogo-pin headers — swap or repair the RF shield without touching the main board.
3× NRF24L01 and dedicated CC1101 for real multi-radio operations instead of time-slicing one chip.
Redesigned IR front-end after the v1 receiver limitation.
WS2812 NeoPixels ×4 for status feedback and buzzer for audible alerts.
Everything now stored/updated via microSD and OTA, including firmware and scripts.
