Only missing thing is the description of the jumper block

One of the great product for IOT, which gives huge opportunity to explore many things, This tiny module less than $5 module can be used as a standalone device for controlling devices without going for a microcontroller to support it, thanks for the lua firmware, I bought this product without any knowledge about it , icstation provides the needed materials to get start with this prodcut, I am a returning customer for icstation, you guys doing an awesome job, Thanks for the fastest shipping and attend all my queries . I would recommend my fellow electronic lovers to take a look into your site

Great kit, smd soldering is not as hard as it seems! Shipping took a while but hey the kit is great and the matrices are linkable

Hello, i've bought four pices of them by you. but i have a problem, that a lot of dots are instantly shining. Does anybody knows what I've done wrong? Greetings Andreas

Quick shipping and good packaging (the pins were all fine) The product works out of the box and is an excellent value

cheap with high quality, use it for my smart car project.

Great product. Used it t monitor gates movement opening and closing. The wire is very long, 8 feet or almost 2.5m so is usable for long distance. I also tested with a longer wire add on, and the sensor works for longer distance in my case almost 10m of wire between sensor and the board. Great product and price for a waterproof sensor, would buy it again!

I got today my first shipment from icstation. There was the HC-SR04 Sensor included what I have ordered as a replacement for a CJMCU-89. A bit later and my quad works fine with the icstation HC-SR04. Great!

Great boost modules. Works well with 2x AA rechargeable batteries as supply voltage with a 3.3V or 5V output for an MCU. Only drawing .09mA @ 3.3V and .15mA @ 5V of quiescent current. Also works well boosting 2x AA rechargeable batteries to 10V for powering 2 x 7020 3 LED segments in parallel for a small light. Only drawing .45mA of quiescent current @ 10V. Thanks!!!

Works perfectly with Arduino Nano. I tested it with Arduino Uno too. You can adjust the sensitivity of the sensor very good, and it works well. The sensor is very very powerful on this PBC. I use it to sense my cat and to trigger ultasound. I call it "Cat-Stopper". But the ultraound have to be cange from time to time, because my cat become accustomed to the one frequence sound :)
