keyestudio micro bit Capacitive touch Module

The keyestudio micro:bit Capacitive Touch Module is an easy-to-use digital sensor designed to replace traditional mechanical buttons with modern touch control. It is perfect for South African students, educators, and makers looking to build interactive projects using their micro:bit boards.

Easy crocodile clip connections

The module features six connection rings, including two ground rings, two 3V power rings, and two signal rings mapped to pins 0, 1, and 2. This layout allows for quick, solderless hookups to your micro:bit using standard crocodile clip lines.

Reliable digital touch sensing

Utilising a specialised touch detection IC, this module replaces mechanical buttons with a variable area key that outputs a clean digital signal. It offers low power consumption and operates reliably across a wide voltage range.

Automatic self-calibration

Upon powering up, the module performs a quick 0.5-second self-calibration during which it should not be touched. If left untouched, it automatically recalibrates every 4.0 seconds to maintain optimal sensitivity.

Real-world applications

Capacitive touch technology is widely used in everyday electronics like laptop trackpads, mobile phones, and tablets. This module lets students explore these real-world interfaces in their own DIY builds.

Onboard LED indicator

When the sensing area is touched, the module sends a HIGH level digital signal to the micro:bit and illuminates its onboard LED. This provides immediate visual feedback for testing and debugging your code.

Compact and lightweight specifications

Operating at DC 3.0V to 3.3V, this ultra-lightweight 1.7g module measures just 31mm by 27mm with a thickness of 2.5mm. It is fully ROHS compliant, making it a safe and compact addition to portable projects.
