Product Description:
This little board does all the neat tricks of the Arduino: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx are familiar, running at 16MHz and 5V, will remind you a lot Other Arduino compatible boards you like, but this product can go anywhere, has a voltage regulator on board, so it can accept voltages up to 12VDC, if you're on a power board with an unstable supply, be sure to connect it to the " RAW" not the VCC pin, this latest version fixes the silk bug so that pin 14 is correctly labeled, we also added a PTC fuse and diode to protect the power circuit and corrected the RX and TX LED circuits
