### Schematic
![Schematic](https://raw.githubusercontent.com/xyzroe/16-relay-Zigbee/main/hardware/Schematic.png)

#### Jumpers
Due to the fact that the Zigby module has only 16 free pins, you have to give up some relays if you need to use input pins or sensors.

**Relays that always connected:**  
D7 - Relay 1  
...  
D11 - Relay 5   
D14 - Relay 6   
D18 - Relay 7    
D19 - Relay 8

**Relays with jumpers:**  
D20 - Relay 9  
...  
D27 - Relay 16

![Jumpers description](https://raw.githubusercontent.com/xyzroe/16-relay-Zigbee/main/images/jumpers.png)  
**RED** - isolated digital input on X1,X2  
**GREEN** - relay boards on X0  
**YELLOW** - direct IO on X3, X4

*JP - connect DS18B20 to CC2652 TDI_D17 (may lead to the inability to flash using DEBUG)*  
*LED always connected to TDO_D16*  
*Button always connected to D15 (BSL or SBL pin)*

#### Inputs
**SOLDER ONLY ONE COLOR**  
![Inputs description](https://raw.githubusercontent.com/xyzroe/16-relay-Zigbee/main/images/inputs.png)  
**RED** - HIGH VOLTAGE control (5-300 AC/DC) **Electrical Hazard Risk**  (220V in schematic table)

**YELLOW** - low voltage control (GND) (5V in schematic table)

### Firmware - PTVO
In most cases, you will need the premium version, but it also works great on the free version.
Below is one of the configuration options with 10 relays, 4 inputs, 1 button, DS18B20 and DHT22.

### Flashing
CC2652 comes with firmware with Serial bootloader (SBL) activated, so you don't need J-Link.   
I prefer to use [ZigStarGW-MT](https://github.com/xyzroe/ZigStarGW-MT), but you can also use cc2538_bsl.py or Flash Programmer 2.

***Don't forget to activate SBL while making your firmware, otherwise you will need J-Link programmer to reactivate it***

### 3.3V relay board mod
Some revisions of 16-channel relay boards cannot control using 3.3V voltage, because, built-in optocouplers are powered by 5V.
Such boards need to be slightly redone - to separate the power supply of optocouplers from 5V and apply 3.3V to them. Learn your board schematic for more.

An example of where you can take 3.3V is in the photo below (AMS1117).

### Binding
The firmware supports direct binding on input and output endpoints.
