📄️ Haptic Motor Driver Module
Haptic Motor Driver Module is a module that can be used to drive a haptic motor. The module is based on the DRV2605L haptic motor driver IC. The DRV2605L is a versatile haptic driver that can be used to drive a linear resonant actuator (LRA) or an eccentric rotating mass (ERM) motor, providing a wide range of haptic effects. The module is designed to be used with compatible STEMMA QT connectors and qwiic connectors.
📄️ LiPo Charger Boost & I2C Monitor
The UNIT LiPo Charger Boost & I2C Monitor is an advanced charging and monitoring module for single-cell LiPo batteries (3.7V to 4.2V). It integrates a TP4056 charger, an MT3608 voltage booster with output limited to 27V, and a MAX17048 battery monitor over I2C. This module is ideal for applications requiring efficient charging and real-time battery monitoring.

Description
📄️ Relay Module
This dual-channel relay module is engineered to safely and reliably interface with microcontrollers that manage higher-voltage or higher-current loads. It provides a dedicated 5 V supply for powering the relay coils while the logic supply is aligned with the microcontroller’s I/O voltage (3.3 V or 5 V). The module accepts digital control signals to toggle the relays, and the relay contacts are designed with both normally-open (NO) and normally-closed (NC) configurations, offering versatile switching options.
📄️ CN3165 Battery Charger Module
This compact printed circuit board is designed to serve as a single-cell Li-Ion battery charger and power-out module. Its USB-C interface provides 5 V from any compliant source, powering an on-board charger IC that supports charging currents of 250 mA, 750 mA, or 1 A. Two sets of screw-terminal outputs are available:

📄️ PWM Module
This two-channel PWM module PCB is designed to amplify pulse-width modulation signals generated by a microcontroller, enabling the switching of external loads at voltages and currents well above the microcontroller’s native limits.
📄️ Boost Converter Module
The Boost Converter Module is a compact, adjustable DC–DC step-up (boost) regulator designed to increase a lower input voltage to a higher output voltage. It is powered by the TPS61023 high-efficiency switching regulator from Texas Instruments, enabling reliable operation even from low-voltage sources such as LiPo batteries or solar panels.
