P1 rx
About the P1 rx PCB
P1 rx is an open source PCB design by Deco025, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 75 × 60 mm, with 86 components from 44 distinct parts.
Other key parts include the UCC27211, INA240A2D, LM74700, LMR16006X and TC2185-3.3. By type, the board carries 40 capacitors, 19 resistors, 9 diodes, 7 ICs, 4 connectors and 4 inductors.
It belongs with the power & battery and iot & wireless designs in this gallery.

- 发射端过流保护：INA240 输出同时进 ADC 和片内比较器（COMP1），比较器直接触发 HRTIM 故障关断。 - 接收端过流保护：充电电流进 ADC 和片内比较器，比较器阈值用片内 1.19 V 基准，对应约 11.9 A。 - 防倒灌：同步 Buck 上管的体二极管会让超级电容反向放电到 VRECT，所以输出端串联 LM74700 + N-MOS 理想二极管，由 MCU 的 CHGEN 控制。 - 接收端的辅助电源只从 VRECT 取电。小车离开发射线圈后，接收端 MCU 掉电，Buck 停止，理想二极管关断。 - 发射与接收的地完全隔离（GND / GNDRX）。
