looks fine, powered up, conected to the device. the web interface is good. still haven't got the reader to test it fully. the only problem is that even at 9 volts the voltage regulator and the metal wifi module get really hot in 2 minutes. i really don't know how it would handle 18 volts as stated in the description. definetly will be good to be used with a buck converter if it needs to be used with more than 5V
when you read from wiegand 26 and yo want to get the card number in decimal you have to take the 26 bit binnary number from the read, copy it without the very first and very last bit and convert it to decimal.
