Paid USD 1.53 - a total bargain as postage included. Ordered 02-04-2018 delivered to my UK address 13-04-2018 (11 days order to receipt). Module has 6 pins labelled with board printing on underside as follows: 1. 5V 2. VCC 3. 3V3 4. TXD 5. RXD 6. GND A shorting jumper was supplied with the module - but as supplied it was shorting pins 4 (TXD) and 5 (RXD). I note that the module shown in the main description photo shows the jumper shorting pins 2 (VCC) and 3 (3V3). I assume that the position of the shorting jumper is used to change between 3.3V and 5V operation. The entire board is coated with a transparent heat shrink sleeve giving the board a certain level of insulation/protection from external entities. I have yet to power up this module and put it to work (reflashing Sonoff modules with Tasmota firmware) - but at present confidence level is high!
