ESP32-C3 Mini Development Board

Added to your shopping cart

The ESP32-C3 Mini Development Board is an entry-level development board based on ESP32-C3-MINI-1, a module named for its small size. This board integrates complete Wi-Fi and Bluetooth® LE functions.

Most of the I/O pins on the ESP32-C3-MINI-1 module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C3-DevKitM-1 on a breadboard.

ESP32-C3 Mini Development Board Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    Will this development board handle battery charging (lithium ion)?

  • Irgski / about 3 years ago / 1

    To clarify, this ESP32 module requires a USB MicroB connector (like Sparkfun PN: CAB-13244) and NOT a USB micro-B superspeed connector (like Sparkfun PN: CAB-14724) - Is that correct?


  • dekip / about 3 years ago / 1

    Right now, there should be support for ESP32-C3 through Arduino IDE. I am waiting for my C3, so can not approve it. ESP32-S2 works like a charm with Arduino IDE.

RISC-V future

I believe this is the future of computing. RISC-V is a verifiable architecture with scalability. This test platform gives a good processor to train on. Anyone used to Arduino(-ishes) can easily pick up on the ESP32-C3 and add some skills for this up-and-coming processor. RISC-V SoCs are available in almost every form factor, for compatibility with existing Hats.
