Review: It is working board the stress resistance is not checked. has some small differences with the original wemos, has more угловатую shape. Distribution range signal is not checked. made the photo for comparison with wemos.
Review: Fast shipping, arrived in 3 weeks. Sealed anti-static bag inside a padded envelope. The module is an ESP-12F with the SPI pins exposed but not broken out. Tested to be working fine, but you need the drivers for the CH340 serial converter. Comes with a set of 3 different types of headers you can use! Very satisfied and recommended.
