    The board uses GPIO 0 to drive the relay. Unfortunately this means that this pin is held low on power up which puts the ESP01 into boot from serial link mode. To avoid this I added a 3.3K pull-up resistor to this pin. You also need to connect the CH_PD pin to +ve. The relay chatters on power up which appears unavoidable and may be a problem in some applications.

    ESP01 does not boot with this module. One small modification and its resolved: solder an 10K resistor between GPIO0 and 3,3v. ESP01 boots up just fine, and no clicking relais on poweron. You also need to connect the CH_PD pin to +ve.
