jadenvv/NULL1A version of a flipperzero that has the same capabilities of Sub-GHz RF, IR, Wifi, and NFC/RFID
NULL is an open-source printed circuit board by jadenvv, from the jadenvv/NULL repository on GitHub. It is a 4-layer board of 40.5 × 80.2 mm with 121 parts on 113 nets, routed with 1,034 tracks and 257 vias.
It is built around the ESP32-S3, PE4259-63 and SX1262IMLTRT, with the TPS61222DCK, W25Q32JVSSIQ and 0900FM15K0039E among its other parts. Its parts include 60 capacitors, 26 resistors, 9 ICs, 8 inductors and 5 switches. It belongs with the radio and wireless boards and the ESP32 boards of this library.
NULL is a ESP32-S3 based PCB board with capabilities of infrared emulation, RFID transceiving, ARP-spoofing on WiFi Networks, and LoRa Puck capabilities. Developed with a mixture of the ESP-IDF development environment
The origins of the development of NULL really came out of the intrigue of the flipper zero. I wanted to create a cheaper alternative to what seemed like an amazing development board for pentesting enthuastist. And, not only did I create a cheaper alternative for myself, but added an additional feature of a LoRA puck boosting the overall usefullness of the board.

It measures 40.5 × 80.2 mm and has 4 copper layers, 1.6 mm thick.
121 parts, built around the ESP32-S3, PE4259-63, SX1262IMLTRT and TPS61222DCK. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the jadenvv/NULL repository on GitHub, at the commit this page was made from: the board is null_elec/null.kicad_pcb and its schematic null_elec/LIB_TRF7970ARHBR/TRF7970ARHBR/KiCad/NULL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask jadenvv before reusing the design.
