Description & Specifications

The CodeCell C6 is a compact electronic development module measuring just 18.5 mm wide. It features an Arduino-compatible ESP32-C6 microcontroller with Wi-Fi 6, Bluetooth Low Energy 5 and Zigbee connectivity, enabling wireless control through compatible platforms such as Home Assistant and the MicroLink app.

CodeCell integrates battery charging and power management, ambient-light and proximity sensing, and a BNO085 9-axis motion sensor. It provides six programmable GPIO pins, I²C connections 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.

CodeCell C6 electronic development module

The VCNL4040 measures ambient light and proximity at distances of up to approximately 20 cm. The BNO085 combines a 3-axis accelerometer, gyroscope and magnetometer with onboard sensor fusion. It can provide orientation, motion state, activity classification, acceleration, tap detection and step-count data.

CodeCell C6 supports timer-based wake-up and interrupt-based wake-up from changes in light, proximity or detected taps. This makes it suitable for low-power projects that only need to wake in response to specific events.

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 C6, four M1.2 screws, three sets of female headers and a 1.25 mm battery cable. The optional battery configuration also includes a 170 mAh, 3.7 V LiPo battery with a pre-fitted connector.

Safety & Use

CodeCell C6 is a low-voltage electronic development module intended for DIY projects, prototyping and educational electronics. It is not a toy or a finished standalone appliance.

Power CodeCell through USB-C or a compatible single-cell 3.7 V rechargeable LiPo battery.
Check the battery connector polarity before use. Do not connect a damaged, swollen or leaking battery.
Avoid short circuits, liquids, excessive heat and contact between exposed connections and conductive objects.
Do not exceed the electrical ratings shown in the specifications. External motors or other high-current devices may require a suitable driver and power supply.
Disconnect power before soldering or modifying connections. Young makers should work under responsible adult supervision.
The supplied screws, headers and battery cable are small parts and should be kept away from young children.

When integrating CodeCell into a completed project, the maker is responsible for ensuring that its battery, power supply, wiring, connected devices, mounting and enclosure are safe and suitable for the intended use.

Frequently Asked Questions

How do I get started?

Tutorials and example projects are available on the CodeCell Tutorials page.

In the Arduino IDE, open Sketch → Include Library → Manage Libraries, search for “CodeCell” and install the latest version.

After installation, open File → Examples → CodeCell. We recommend starting with the GettingStarted example, which introduces the module’s main sensing functions.

How can it wake up from sleep?

CodeCell C6 supports RTC-timer and interrupt-triggered wake-up options. Typical sleep currents are:

RTC timer: Approximately 40 µA
Proximity interrupt: Approximately 425 µA
Darkness interrupt: Approximately 290 µA
Brightness interrupt: Approximately 290 µA
Tap interrupt: Approximately 820 µA

Battery life depends on the battery condition, selected sleep mode, wake-up frequency, active operating time, wireless activity and all connected components.

A basic estimate can be calculated using:
Battery life (hours) = battery capacity (mAh) ÷ average current (mA)

For example, a 170 mAh battery using RTC-timer wake-up could theoretically provide approximately six months of standby time. Actual battery life will normally be lower because active operation, wireless communication and connected components must also be considered.

What ages is it suitable for?

CodeCell is an electronic development module designed for makers, students and engineers. It may require wiring or soldering. Young makers should only use it under responsible adult supervision. The package also contains small parts that must be kept away from young children.

Does it support MicroPython?

The ESP32-C6 supports MicroPython. However, the official CodeCell library is written in C++ for the Arduino environment. MicroPython users may need to create or adapt drivers for the onboard sensors and peripherals.

What about the BOOT pin?

CodeCell normally enters programming mode automatically through its USB serial interface, so dedicated BOOT and reset buttons are not required.

If a program causes the module to reset continuously, it can be placed manually into programming mode:

Disconnect USB power and switch off or disconnect the battery.
Connect the SCL pin to GND.
Reconnect USB power.
Upload corrected firmware.
Disconnect power and remove the connection between SCL and GND.
Reconnect power normally.

What information can the motion sensor provide?

The BNO085 combines a 3-axis accelerometer, gyroscope and magnetometer with onboard sensor-fusion processing. Depending on the selected operating mode, it can provide:

Orientation, including roll, pitch and yaw
Motion and stability classification
Activity classification
Acceleration and linear acceleration
Gyroscope and magnetometer readings
Gravity vector
Tap detection
Step counting
