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.

Good, sturdy framework.
Assembly was not bad. Lay out all of your marked pieces, follow instructions and match up all supplied screws, etc.

Don't Waste Your Money
Bought this 2 year protection plan and come to find out it doesn't even cover simple stuff like our mattress losing it's shape and stability. A mattress should last longer than 1 1/2 years before it starts caving in and the foam and springs start to give. So disappointed. Asurion Protection is a waste of money.
