ESP32-C6 ESL PCB Design

Design a compact, ultra-low-power Electronic Shelf Label (ESL) PCB using an ESP32-C6 SoC.

Include:

ESP32-C6 with 40 MHz crystal + load capacitors
External SPI Flash memory
SPI e-paper display connector: CLK, MOSI, CS, DC, RESET, BUSY
2 × CR2450 coin-cell batteries
Efficient low-Iq power-management circuit for long battery life
ESP32-C6 EN/RESET and BOOT circuitry
Exposed pogo-pin programming pads: 3.3V, GND, TX, RX, EN, BOOT
2.4 GHz PCB antenna with proper RF keep-out
Decoupling and bulk capacitors near all ICs
Compact 4-layer PCB with solid GND plane
Optimize all circuitry for minimum sleep current and battery leakage
Follow the ESP32-C6 reference design and recommended RF/PCB layout guidelines.

Thought for 3 sec

No design changes were made. The project remains blank with 0 components and 0 nets; the ESP32-C6 schematic, power architecture, e-paper interface, programming pads, antenna keep-out, and 4-layer PCB layout are still to be created and verified against Espressif guidance.

Execution stopped because your ACUs ran out.
