Ruth's sister ESP32-DevKitC-32 development board

SKU CH-2CBB-N7J3N

ESP32 development board with dual-core processor, integrated Wi-Fi and Bluetooth, CH340C USB interface, 4 MB flash, 520 kB SRAM, and 5–12 V external power input

  • Dual-core 32-bit MCU handles Wi-Fi and Bluetooth tasks
  • 520 kB SRAM plus 448 kB ROM for program storage
  • 4 MB external flash holds firmware and data
  • CH340C USB driver gives reliable high-speed downloads
  • Three power options: USB, 3.3 V or 5-12 V VIN

ESP32-DevKitC-32 development board

This ESP32-DevKitC-32 board integrates a dual-core 32-bit MCU with WiFi and Bluetooth for embedded projects. It suits developers, students and hobbyists who need a compact platform for IoT prototyping. The board measures 51.77x28.45mm and weighs about 9.5g. It supports Arduino IDE, Mixly and Mind+ programming environments.

USB-C CH340C power and thermals

The board uses a USB-C connector with CH340C driver chip for stable communication and power delivery. It accepts VIN input from 5-12V, USB power or external 3.3V supply, with a battery version limited to 5.5V maximum. Ultra-low power design keeps heat and noise negligible during normal operation. Integrated 520-kB SRAM and 448-kB ROM support efficient processing.

Sustained load behaviour

Under continuous operation the dual-core ESP32-DOWDQ6-V3 maintains performance with 4MB external storage for firmware and data. The 16-kB RTC SRAM preserves state during deep sleep cycles. Wide voltage input range ensures stable operation across varying supply conditions. This board is not for builders who need more storage or higher I/O counts than the module provides.

Questions about this item

How do I install the ESP32-DevKitC-32 board in Arduino IDE, and which step do people often miss?

Add the ESP32 board manager URL in Preferences, install the esp32 package via Boards Manager, then select ESP32 Dev Module; the step often missed is pressing the BOOT button while clicking Upload to enter download mode.

What maintenance or replacement will the CH340C USB driver chip need later?

The CH340C driver may require a reinstall after major OS updates; the board itself has no user-serviceable parts, so only the USB cable might need replacement if it wears out.

What limit appears first when the ESP32-DOWDQ6-V3 dual-core MCU runs sustained workloads?

Thermal throttling from the 520-kB SRAM and 448-kB ROM activity under continuous dual-core operation typically limits performance before the 4MB flash or 3.3V supply becomes a bottleneck.
