Designed by Cirket open-source hardware in China, the ESP32-DIV V1 is a handheld wireless pentesting and experimentation tool with Wi-Fi, BLE, generic 2.4 GHz (NRF24), and Sub-GHz RF (CC1101) communication. The device targets hardware hackers and cybersecurity researchers for learning and testing wireless vulnerabilities across multiple frequency bands. The device features a modular “sandwich” design consisting of a Main Board and a Shield Board connected via a 20-pin header. The Main Board integrates an ESP32 microcontroller, a 2.8-inch ILI9341 TFT display with XPT2046 touch controller, SD card slot, battery charging and power management, and navigation controls. The Shield Board hosts the RF hardware, including three NRF24L01 modules, a CC1101 Sub-GHz transceiver, and multiple SMA antenna connectors. ESP32-DIV (V1) specifications: Wireless Module – ESP32-WROOM-32U SoC – ESP32 dual-core wireless microcontroller CPU – Dual-core Xtensa 32-bit microprocessor @ 240MHz Memory – 520KB internal SRAM Wireless – Wi-Fi 802.11b/g/n, and Bluetooth (4.2 and […]
