The MCP466X devices are dual channel, non-volatile, 8-bit (257 wiper steps) digital potentiometers with EEPROM and an I2C compatible interface. The MCP466X family is available with end-to-end resistor values of 5KΩ, 10KΩ, 50kΩ and 100KΩ. These devices offer WiperLock™ Technology which allows the user unlimited reprogramming and locking of the wiper setting. It is useful for equipment that requires factory trimming or recalibration. The MCP466X devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count.

| Brushless 22 Click is a compact add-on board suitable for controlling brushless DC (BLDC) motors with any MCU. This board features the MTD6508, a 3-phase full-wave sensorless driver for BLDC motors from Microchip Technology. It features 180° sinusoidal drive, high torque output, and silent drive, rated for an operating voltage range including both mikroBUS™ power rails, and comes with speed control achieved through pulse-width modulation (PWM). Besides, it features several diagnostic circuits and drive-control functions such as motor lock protection, overcurrent limitation, and thermal shutdown protection. This Click board™ makes the perfect solution for home appliances and industrial equipment, such as cooling fans.
Brushless 22 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket. |
| Smart Buck click is the two-channel step-down DC/DC converter and regulator, with plenty of additional functions. It can provide voltage measurement at each of its two programmable voltage outputs, as well as the measurement of the current consumption. In addition, it can also provide power consumption measurements of the Click board™ itself, both at the mikroBUS™ +5V power rail, and the external voltage input terminal. Finally, there is 2kbit of EEPROM at disposal, which can be used for logging the measurements, storage of the working parameters, or any other type of general purpose data. |
