The CodeCell C3 Light is a compact electronic development module measuring just 18.5 mm wide. It combines an Arduino-compatible ESP32-C3 microcontroller with Wi-Fi 4, Bluetooth Low Energy 5, USB-C programming, LiPo battery charging, ambient-light sensing and proximity sensing.

It provides six programmable GPIO pins, including ADC and PWM functions, together with I²C and multiple power connections for compatible modules, sensors and actuators.

The module can be powered through USB-C or a compatible single-cell LiPo battery. USB-C supports programming, serial communication and battery charging. The BQ24232 power-management IC allows the battery to charge while the project continues operating.

The onboard VCNL4040 is an infrared-based sensor that measures ambient light and proximity at distances of up to approximately 20 cm. This makes the C3 Light suitable for interactive lighting, touch-free controls, automatic brightness adjustment and compact IoT projects.

The CodeCell.h Arduino library provides ready-to-use functions, tutorials and example projects. CodeCell can also connect to the MicroLink app for wireless controls and real-time sensor feedback.

Each box includes one CodeCell C3 Light, four M1.2 screws, a battery-cable and three sets of female headers. Depending on the selected variant, the headers are supplied unsoldered or pre-soldered. The Battery Cable variants include a 1.25 mm battery cable. The battery variants include a 170 mAh 20C, 3.7 V LiPo battery with a pre-fitted connector. The battery measures approximately 23 × 17.5 × 8.7 mm and weighs approximately 4.6 g. Its datasheet is available here.

CodeCell C3 Light is an electronic development module intended for integration into prototypes and DIY electronic projects. It is not a finished standalone appliance or a toy. Supporting compliance records are maintained for the PCB assembly, specified components and supplied accessories. The designer or manufacturer of any completed product incorporating CodeCell C3 Light is responsible for assessing that finished product against all applicable safety, radio, EMC, environmental and other regulatory requirements. For commercial product integration, please get in touch.

• Power CodeCell through USB-C or a compatible single-cell 3.7 V rechargeable LiPo battery.
• Check the battery connector polarity before connecting it. Reversed polarity may damage the module or battery.
• Do not use a battery that is swollen, punctured, damaged, leaking or unusually hot.
• Do not short-circuit, crush, puncture, disassemble or expose a LiPo battery to fire, excessive heat, liquids or conductive objects.
• Charge the battery on a stable, non-flammable surface and do not leave it charging unattended.
• Use a battery suitable for the module’s approximately 90 mA charging current and the expected current demand of your completed project.
• Do not exceed the electrical or current limits shown in the specifications.
• Motors, actuators, high-power LEDs and other high-current loads may require a separate driver and power supply. Do not power them directly from a GPIO pin.
• Disconnect power before soldering, modifying wiring or connecting external components.
• Prevent exposed contacts from touching conductive surfaces. Use suitable insulation or an enclosure where appropriate.
• When possible, handle the module using appropriate electrostatic-discharge precautions and operate it in a dry environment.
• The supplied screws, headers and battery cable are small parts. Keep them away from young children.
• Soldering should be performed in a ventilated area using suitable eye protection. Young makers should only use the product under responsible adult supervision.
• Sensor readings and wireless connections must not be relied upon for medical, emergency, protective or other safety-critical functions.
• CodeCell C3 Light must not be connected directly to mains electricity.

CodeCell C3 Light is a low-voltage electronic development module intended for DIY projects, prototyping and educational electronic projects. It is not a toy or a finished standalone appliance. When integrating CodeCell C3 Light into a completed project, you are responsible for ensuring that the battery, power supply, wiring, connected devices, charging arrangement, mounting and enclosure are safe and suitable for the intended use.

Orders are dispatched from Malta and are available for international shipping to supported destinations. Available shipping methods, estimated delivery times and shipping costs are displayed at checkout. Deliveries outside the European Union may be subject to local import duties, taxes or customs fees.

Orders containing the optional LiPo battery are subject to carrier, destination and dangerous-goods transport restrictions. Therefore, some shipping methods or destinations may not be available for the battery configuration.
