Qwiic Keypad - 12 Button - SparkFun COM-15290
Keyboard module with ATtiny84 microcontroller . In firmware, the FIFO stack stores the last 15 input data. When the stack is full, all previous input is overwritten. The keypad has a key layout similar to a standard telephone . The resistance range when the button is pressed is 10 Ω to 150 Ω. The product is an element of the Qwiic ecosystem - on the bottom of the module, dedicated JST connectors with a pitch of 1 mm greatly facilitate the prototyping process. The communication module uses the I2C bus .

Qwiic ecosystem
Qwiic Connect by SparkFun is an ecosystem of sensors based on the I2C communication bus, actuators, and cables with dedicated plugs. This solution simplifies the prototyping process. All boards supporting Qwiic use a common, 4-pin JST connector with a spacing of 1 mm. This reduces the amount of space required on the PCB. It also protects against incorrect connection.
