Hello, it really works with 3.3v? Thanks
This one can work well with Linkit ONE, and you don't worry about it.
Hello, I am sorry that this product is designed by one of our supplier and it's not open source.
We don't have the schematics.
THE Maximum Effective Distance of they are different . And Mini 125Khz RFID Module - Pre-Soldered Antenna (70mm Reading Distance) DO NOT support external antenna.
