CJMCU-0401 4-bit Button Capacitive Touch Proximity Sensor Module With Self-locking Function
A part of the review has been auto-translated.
Well packaged and reasonable delivery time (20 calendar days from order). I found it hard to locate a definitive datasheet for this module and note that others on the internet have had similar problems. I am still experimenting but believe the chip is the old ttp224. Everything so far seems to work out OK on that assumption! It seems like a nice unit, but I can't really recommend it at this stage without definitive documentation.
Arrived fast and as described.
Wery good capacitive button for our teaching complet... :)
