I knew they were small, but I didn't wrap my head around how small. They're about the size of a US dime. They work well through 1/4 inch acrylic. I didn't buy them for it, but assuming that rain won't cause too much issue, since they can be put inside an enclosure and still work, they'd probably be great for a control unit out in the weather. Worst case, even though it'd survive getting drenched, it may sense beaded water as a touch.The description is very poorly worded - Jumper pad "A" controls output logic level. When open, it is active High. When shorted, it is active Low. Jumper pad "B" controls switching method. When open, it is momentary output. When shorted, it is toggle output.No one should be honestly surprised that a _sensor_ doesn't have a high current switching capacity. Whatever the sensor is connected to should have the high current capability if needed.My one wish is that the LED had a bridged solder pad to easily enable or disable it rather than having to risk destroying it to "turn it off."

Took a few tries to get use to. Doesn't pass enough current directly for a couple LEDs. However, it works WELL as a HIGH/LOW signal when using a logic level MOSFET. Not as well with NPN BJT because of the current required.The quiescent current when wired to project and off is 4.3uA, so totally satisfactory for a battery project.Active power (latched on, no project load) with board LED is 7mA.Board LED removed, current when on rises from 4.3uA to only 7uA, which is GREAT low power when active.I've only used the latching function, HIGH to turn on. Does in fact trigger without quite touching.They are SMALL, so if wanting a decent sized touch pad for other end users, look elsewhere and choose based in dmiensions.Otherwise, I'd recommend having these around to play with projects without using switches and buttons and dealing with debouncing with hardware or code.

1 year review. Work as advertised. I have them under both a sheet of acrylic and thin cardboard and they still work fine. Observations. When configured as non latching they only stay on about 2 seconds when held. When configured as latching they output for extended periods. Very sensitive. You don’t actually have to touch to activate. Output is only 4v when operating on 5v which is fine for most logic circuits. Output switches between 4v and ground which is nice because I don’t need pull up or pull down resistors on the Arduino side of the circuit (recommend adding then anyway if your wire runs are long, mine are all less than 7”). However a few of them failed when supposed to output ground and had to be replaced, but that could be due to my initially poor soldering skills (which have improved considerably.) When configured for ground output the LED stays on when not activated. Finally you need to supply and attach your own headers, but that allows you to choose both the orientation and type of connection. I’ve soldered both wires and headers to them without issue, save for the possible failures mentioned above. Overall very satisfied.

I soldered the jumper so it would latch high and it seems to stay on with a load, and toggle on/off reliably without adding any components, unlike some similar chips that don't like to turn off. However, I was only able to get about 16-20 mA output, using a 3.7V LiIon cell as input power. The data sheet specified how much power the chip itself would consume but not how much it could carry. It's fine for logic or a couple LEDs but you'll need additional parts to drive a brighter light or heavier load.

El módulo es muy fácil de usar y muy versátil; fabriqué un circuito de 220vac con una fuente capacitiva para alimentar el módulo con 5v y luego a través de un optoacoplador y un Mosfet, sirve para para encender luces de 220v con una línea para tocar que lo activa.
