Versions

There are different versions of almost the same board V1,V2, V2.1 and V3. The differences in the table below:

Issues

Spiking power on the board when plugging in a 2s battery could lead to a broken board on the original design. To preven this from happening as add a capacitor to the battery lead. This capacitor should have an ESR lower than 0.2ohm and have a capacitance of 100uF or higher. A Rubycon ZLG/ZLH series and Samyoung NXB series.

Binding

To bind with your TX follow these steps

1. Connect battery 1. Pres an hold the bind button for about 2 seconds until the LED lits continuous 1. Enter the bind mode via your transmitter menu or bind button 1. The LED starts blinking as soon as binding was successful 1. Unpower battery, repower, start flying
