Frequently asked about this product
Which programming environments work with the ESP32-C3 Mini IoT Board?
The ESP32-C3 Mini IoT Board is supported by the mainstream maker toolchains: Arduino IDE (C/C++), Mixly and Mind+ (graphical), plus Scratch/mBlock for younger learners. Sample code and lessons ship with the product, and the board follows the standard pinout so existing shields and modules connect directly.
What voltage does the ESP32-C3 Mini IoT Board run on?
The ESP32-C3 Mini IoT Board runs from a standard 3.3-5 V DC supply (USB or the controller’s 5 V rail). It draws only a few milliamps in normal operation, so it is safe to power from the controller board itself for classroom builds.
What projects is the ESP32-C3 Mini IoT Board good for?
The ESP32-C3 Mini IoT Board is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
