ESP12-E Dev Board

My mission would not be complete unless I included a similar type of board for another one of my go-to ESP chips, the humble old 12-E. It may be a bit old, and largely regarded as obsolete by many, but I still find this an extremely useful, cheap solution for many of my applications. Having fewer available GPIO pins, I have opted to provide a jumper to enable/disable the I2C pull-up resistors on this PCB, as well as provided a jumper to GPIO16 in case you wanted to use the Wake-up function in low-power ( deep-sleep mode). Standard Reset and flash buttons are also provided, as well as a clearly labelled pinout on the silk screen. The board can be powered with ideally 7v DC via the VIN pin ( the LDO regulator can handle 15v, but I believe that stresses the component too much, in my view anyway) . Other design features include onboard heatsink for the LDO regulator, big fat tracks for the power inputs and a decent ground plane on both sides of the PCB. PCBWay did a very good job at producing this, thank you !:)
