Leshy2 LESHY2-UI-R2 R2 exact placement
Leshy2 LESHY2-UI-R2 R2 exact placement is an open source ESP32 PCB design by anton-vinogradov: a 6-layer, 80 × 150 mm board with 430 components (84 distinct parts). It is built around the ESP32-S3-WROOM-1U-N16R8, Texas Instruments TPD4E05U06DQAR, KYOCERA AVX CP0603Q5425ENTR, Texas Instruments TPS2553DRVR-1 and more. Filed under rf & radio and iot & wireless and test & measurement.
Open multiband RF handheld on ESP32-S3 + ESP32-C5 — successor to esp32-leshy / ESP32-DIV

Leshy2 is intended to be a hobby device combining spectrum observation, communication, diagnostics and safe experimentation without a mandatory laptop. The first order targets one genuinely working prototype: the factory supplies two populated PCBAs and the owner completes a simple, solder-free final assembly.
