ESP32-C3 SuperMini Expansion Board
Overview
The ESP32-C3 SuperMini Expansion Board is a compact and convenient breakout board designed to extend the capabilities of the ESP32-C3 SuperMini development board. It provides easy access to key I/O pins and essential peripheral interfaces, making prototyping and development faster and more reliable. This board is ideal for IoT, embedded systems, and smart device projects that use the ESP32-C3 RISC-V microcontroller.
With clearly labeled headers and additional onboard components, the expansion board simplifies connecting sensors, actuators, displays, and other modules without the hassle of breadboarding.
With clearly labeled headers and additional onboard components, the expansion board simplifies connecting sensors, actuators, displays, and other modules without the hassle of breadboarding.
One of its standout features is onboard support for a 3.7V lithium battery (PH2.0 interface), including charging capability via USB. A green LED indicates active charging and turns off when the battery is fully charged.
To provide flexibility in powering your projects, the board includes dual voltage outputs (VCC1 and VCC2). By default, both lines supply 3.3V. However, users can configure them to output 3.7V by modifying onboard solder jumpers—simply remove the default 0Ω resistor and bridge the pads with solder to reroute the voltage.

Great product, sturdy and well made. Easy assembly.
Size: 3 Panel, Color: Beige
These are awesome! They were easy to assemble. They are lightweight and easy to move. I was able to easily put all 6 pieces -(I ordered two sets)-into the back of my SUV at once, by myself (and I'm a short, older lady). Quality material. Very sturdy and steady. The first set I opened was a used one and did not include instructions, but it was still very easy to assemble and figure out. I recommend using a battery powered screwdriver. With that, the assembly of all 6 panels took less than 45 minutes.

Defective product
Size: 1 Panel, Color: Black
All screws cannot fit with each connectors. The Allen key provided is useless because it doesn’t fit into screws.

Love it, happy with the price
Size: 1 Panel, Color: Black
I have been using this product for a month now. I'm absolutely thrilled with my new Room Divider. It's has made a significant difference in my home. The divider is not only stylish and well-crafted but also incredibly functional. It has effectively separated my open space into cozy, distinct areas, enhancing privacy. Assembly was a breeze, and it's built to last. This room divider has truly transformed my living space, and I couldn't be happier.
