EWP-Control is an open source RP2040/RP2350 PCB design by haum2002, published on GitHub. It is a 4-layer board measuring 76 × 64 mm, with 93 components from 37 distinct parts.

Its main chip is the RP2350B, from the RP2040/RP2350 family. Other key parts include the ESP32-S3, W25Q128JVSIQ, MT25QL01GBBB8ESF-0SIT, APS51208N-OBR-BD and AD7124-8BCPZ. By type, the board carries 45 capacitors, 23 resistors, 15 ICs, 4 crystals, 2 inductors and 1 transistor.

It belongs with the iot & wireless, wearables and sensors designs in this gallery.

From the project

SmartCoolingv2.1 menggabungkan firmware SmartCooling dengan reka bentuk EWP Controller ini. RP2350B kekal sebagai pengawal keselamatan dan actuator kritikal, manakala ESP32-S3 mengurus UI, Wi-Fi, BLE, diagnostik dan OTA. Kontrak komunikasi neutral-transport berada di docs/SMARTCO

Kontrak komunikasi neutral-transport berada di docs/SMARTCOOLINGV21INTEGRATION.md.

Projek ini dibina untuk berjalan serasi pada kedua-dua ekosistem tanpa perubahan kod:

EWP-Control design files

The KiCad project lives in the haum2002/EWP-Control repository on GitHub; these links point at the commit this page was built from.

EWP-Control: common questions

What microcontroller does the EWP-Control use?

The EWP-Control is built around the RP2350B, from the RP2040/RP2350 family.

How big is the EWP-Control PCB?

The EWP-Control measures 76 × 64 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the EWP-Control?

93 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the EWP-Control design files?

From the haum2002/EWP-Control repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the EWP-Control design in my own project?

The repository has no license, so all rights stay with haum2002. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the EWP-Control without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
