The program is working great, Thanks!
Based on the schematics provided by StevieMK2 I created an intermediate PCB to connect the ESP8266 module 1 to the FTDI232RL board.
N.B.v0.6 had the pull up resistor wired incorrectly, this is only relevant if you are using the header SV3 to control CH_PD.This has been corrected in v0.6+, resulting in an additional via.
