Spectre is a compact, multi-purpose Cyber Tool powered by an ESP32-S3 module.
It integrates amplified CC1101 (Sub-GHz) and nRF24 (2.4 GHz) RF modules, High-Power IR Transmitter and Receiver system, and a stable power design using TI BQ25896 Charger and TPS63802 Regulator.
All of this is mounted on a 6-layer ENIG PCB optimized for low noise and signal integrity.
The board was assembled at home using solder paste, a stencil, and a 65 W USB-C preheater. The reflow process was smooth and clean thanks to the low-temperature (138 °C) solder paste.
Every module on the board has been tested, and all systems operate flawlessly
