Pinout
This page shows the pinout that has been pre-configured in the RapidConnect Lighting & Sensor firmware. For more details regarding peripheral compatibility or the hardware that is included with the RapidConnect Lighting & Sensor Evaluation Board, see the Evaluation Board Schematic page.
Interface Summary
Digital In: PIR Occupancy Sensor, Ultrasonic Occupancy Sensor, Factory Reset Button
Analog In: Light Level Sensor
Digital Out: Network Status LED (PTI_DATA), Relay
Analog Out: PWM
Serial: UART TX, UART RX
Others: nReset, VCC, GND, JTDO, JTCK, JTD, JTMS, JRST, PTI_EN
Pinout Using Z357PA40-SMT Module
Notes:
- All pins have maximum sourcing and sinking current of 4mA.
- EM357 runs off a 3.3V
- (*) indicates ADC capable pin
- (#) indicates PWM capable pin
| Module Pad | Function | Relation to zigbee Features | EM357 GPIO | Hardware Integration Comments |
|---|---|---|---|---|
| 1 | PIR Digital In | When either of the two occupancy inputs are triggered (i.e. this pin or the Ultrasonic Digital In), the Occupancy Sensor Endpoint will update the value of the Occupancy Attribute in the Occupancy Sensing cluster. | PC6 (13) |
|
| 2 | Relay Out | When On/Off commands are sent to the Dimmable Light Endpoint, this output will turn on/off accordingly. | PC7 (14) | OUTPUT - Digital (Active High) |
| 3 | Reserved | PA7 (18)# | Reserved for Future PWM | |
| 4 | VCC (3.3 VDC) | |||
| 5 | nCTS / SPI Slave CLK | PB3 (19)# | Reserved for Future PWM | |
| 6 | nRTS / SPI Select (Host Controlled Handshake Line) | PB4 (20)# | Reserved for Future PWM | |
| 7 | nReset, active low | (12) | ||
| 8 | Network Status LED (PTI_EN) | Used as an indicator for two purposes: Network Status
Identify
| PA4 (26)* | OUTPUT - Digital (Active High) |
| 9 | Reserved (PTI_DATA) | PA5 (27)* | ||
| 10 | JTDO | PC2 (33) | ||
| 11 | JTCK | (32) | ||
| 12 | JTD | PC3 (34) | ||
| 13 | JTMS | PC4 (35) | ||
| 14 | JRST | PC0 (40) | ||
| 15 | RXD | PB2 (31) | UART Serial RX | |
| 16 | PWM Out | When a Level Control command is received, the duty cycle of the PWM pin will be updated to match the intended Level (i.e. 0-100%). | PA6 (29)# |
|
| 17 | TXD | PB1 (30) | UART Serial TX | |
| 18 | GND | |||
| 19 | Ultrasonic Digital In | When either of the two occupancy inputs are triggered (i.e. this pin or the PIR Digital In), the Occupancy Sensor Endpoint will inform the network that Occupancy is "true". | PC1 (38)* |
|
| 20 | Illuminance Analog In | The value conveyed via this analog input will be reported to the network by the Light Sensor. | PB7 (41)* |
|
| 21 | Network Button | When this input is held low for >5 seconds, the application will execute a Factory Reset, leaving the network and clearing all settings. | PB6 (42)* |
