ESP32-C3 radar PCB with TX and RX boards, KiCad sources, Gerbers and manufacturing files

防宿管雷达 PCB 发布说明 日期: 2026-09-12 KiCad: 10.0.6

板卡: - TX: 70 mm x 42 mm, 包含 LD2450 接口和 ESP-NOW 发射端 - RX: 68 mm x 42 mm, 仅包含 ESP-NOW 接收端和 LED

设计要点: - ESP32-C3-WROOM-02 天线区悬出板边，减少 PCB 尺寸并保持天线净空 - 1S 18650 电池输入，无充电功能 - MT3608 升压到 5V - AP2112K-3.3 给 ESP32 供电 - 双层板，底层 GND 铺铜 - Freerouting 2.4.1 自动布线，单线程模式 - 最终 DRC: 0 个未连接焊盘，0 个电气错误，剩余仅为丝印边缘提示

生产文件: - TX/gerber, TX/drill, TX/position - RX/gerber, RX/drill, RX/position - BOMcommon.csv - TX/DormRadarTX.kicadpcb - RX/DormRadarRX.kicad_pcb

DormRadar RX: common questions

What microcontroller does the DormRadar RX use?

The DormRadar RX is built around the ESP32-C3-WROOM-02-N4, from the ESP32 family.

How big is the DormRadar RX PCB?

The DormRadar RX measures 68 × 42 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DormRadar RX?

23 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the DormRadar RX design files?

From the gancaokuai/dorm-radar-pcb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the DormRadar RX design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which gancaokuai chose for the repository.

Can I test firmware for the DormRadar RX without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
