- | You have to decide on the LEDs you want to use. Depending on the type, you have to use different resistors **R13, R14, R15** for the LEDs. See the corresponding part in the [[rgb_dimmer|RGB Dimmer]] description about recommended values. | + | You have to decide on the LEDs you want to use.

* **RFM12B:** You should also check the voltages first before soldering the module. At the place for the radio module the pad beside the antenna and at the opposite side the third pad should read about 3.3 V. For soldering, read [[rfm12b_soldering|the RFM12B mounting instructions]]. | * **RFM12B:** You should also check the voltages first before soldering the module.

+ | ===== Modification of PCB rev. 1.0 ===== | ||
+ | |||
+ | In the initial PCB, the blue LED channel is connected to PD7 (OC2A, pin21). To use the same code as for the RGB Dimmer, this needs to be rewired to PD6 (OC2B, pin20). Cut the connection at the bottom of the PCB and make the new connection with a wire. | ||
+ | |||
+ | The status LED has to be rewired from initial PB2 (pin3) to PD7 (pin21), also to use the same code as in all other devices for the status LED. This can be done easiest by connecting the resistor R1 to a wire and connecting the wire to PD7. | ||
+ | |||
+ | In future PCB versions, this shall be changed in the schematic and layout. | ||
