Breaks out ESP-01 form factor 8 pin header to breadboard, etc. V2.0 NOT YET TESTED!!! Made for the Perth Artifactory. - 3V3 regulator circuit. Supply from FTDI Friend, external supply or bread board. Diodes on each input, so no back feed. - Programming section snaps off, if required (need to fit link in this case). - "Reboot" button pulls base of PNP transister high, thus dropping supply to ESP module (required for programming). - "Program" link will also take small form factor toggle switch. - GPIO2 LED circuit for testing - link required. - CH_PD tied to 3V rail, but broken out at link marked "CH" for cutting if required.
