  • Hobby Components Lithium...

    £2.08

    The Hobby Components micro charger is a tiny single cell (3.7V) lithium battery charger module which not only incorporates both battery charging protection and control, but also includes battery voltage & current over discharge protection and battery overload protection. Measuring only 27 x 14mm this tiny module can easily be incorporated into low power lithium battery applications.

    The charger will accept power from either a 5V microUSB adapter or via a 4.5 to 6V power supply and will charge a connected single cell lithium battery at a rate of ~0.5A.

    The battery can be connected via a JST XH-2.54 connector or by 2 large solder pads (BIN + & BIN -).

    The module's output supplies the batteries nominal output of 3.7V (4.2V whilst charging) at a constant current of up to 2A (depending on battery and charger specification). An external device can be connected to this output via a 0.1” pitch pin header or via 2 large solder terminals (BOUT + & GND).

  • Hobby Components ESP-ARGB...

    £7.49

    The ESP-ARGB is a general purpose RGB+W LED light controller based on the popular Expressive ESP8266 wireless microcontroller. It combines an ESP8266 ESP-07 wireless module with four MOSFET transistors. These transistors are connected to the ESPs PWM output pins making it easy to perform independent power control of up to 4 connected devices. Each transistor can switch up to a maximum current of 2A and a maximum voltage of 12V DC.

  • mLink 6 Button Pad

    £4.16

    The mLink button pad is a 6 button keypad with a serial (I2C) interface. The buttons are arranged in a d-pad format (up, down, left, right, plus select and back buttons). They have a tactile feedback when pressed and come with large (11mm) coloured circular keycaps that also make the module ideal for panel mounting. The module can also store up to 16 key presses in its internal buffer meaning that your software does not have to constantly scan the keypad to capture keypresses.

  • ESP32-CAM Programming...

    £3.74

    This adapter board is specifically designed for the ESP32-CAM development board (HCDVBD0041). It allows the ESP32-CAM to be powered and automatically programmed from a computers USB port. It is also fully compatible with the Arduino IDE allowing sketches to be automatically uploaded just like any other Arduino development board.

  • Open-Smart ESP32...

    £6.66

    This development board is based on the popular Expressive ESP32 module. It breaks out all the modules available pins to a convenient 0.1” pitch dual in-line format suitable for breadboarding or other formats of prototyping. It also includes an auto programming circuit (reset button must be pressed after upload to run sketch) which allows the module to be automatically programmed from a computer via its USB type C socket.

  • mLink Character LCD (20x4)

    £7.49

    The mLink Character LCDs are serial (I2C/IIC) LCD displays available in either 16 column by 2 row (16x2), or 20 column by 4 row (20x4) options. Because they use a standard I2C interface they are compatible with most microcontrollers including Arduino, are addressable (address can be changed in software), and only require 2 data pins for communication. Unlike standard serial or parallel character displays they require no configuration or setup to use them saving on development time and code size.

  • mLink 4x4 Matrix Keypad

    £6.66

    The mLink 4x4 matrix keypad is a panel mountable serial (I2C/IIC) 16 key tactile keypad. On the rear of the keypad is mounted a mLink module which continuously scans the keypad (with automatic debouncing) for any key presses. If a key is pressed the module stores the key as an 8 bit ASCII value which can then be read out of its serial interface. It is compatible with other mLink or standard I2C modules allowing you to daisy-chain several different types of modules together using only the two I2C pins of your microcontroller.

  • mLink NTC Temperature Sensor

    £3.33

    The mLink NTC temperature sensor is a serial (I2C/IIC) module that interfaces to a wired remote NTC temperature sensor probe (supplied with module). The module continuously takes measurements from the sensor probe and provides the results as a temperature in degrees centigrade via its serial I2C interface. It is compatible with other mLink or standard I2C modules allowing you to daisy-chain several different types of modules together using only the two I2C pins of your microcontroller. Its default I2C address can be changed via software so that multiple NTC modules can be connected to one microcontroller.

  • SY8205 7 to 30 input,...

    £2.49

    A compact DC to DC power supply module that can accept a wide input voltage range of 7 to 30V (< 24V recommended) with a high current output capability. By default the module will convert the input voltage to a stable 5V output. However by use of solderable pads the output voltage can be changed to either 3.3V, 9V, or 12V should a different voltage be required. Input and output connections are via large solderable pads.
