RPICT7V1 v2.0
RPICT7V1 version 2.0
This is the new version of the RPICT7V1. It now features the same microcontroller as an Arduino UNO. The best of all is the possibility to stack up to 5 boards together to increase the sensor capacity onto one single raspberrypi.
- 7 AC current sensors.
- 1 AC Voltage sensor.
- Compute real power.
- Fit on Raspberrypi 4 holes mounting pattern.
- AtMega328 Mcu (Arduino UNO)
- MCP3208 ADC
- Stackable (5 boards together)
Recommended sensors
- AC Current sensor: SCT-013-000
- AC Voltage sensor:
- UK: 77DB-06-09
- EU: 77DE-06-09
- US: 77DA-10-09
Stacking Configuration
5 boards can be stacked together to offer up to 35 SCT sensors capacity on one Raspberrypi.
In the stacked configuration only one board has a Microcontroller which is the Master board. For the slave board the microcontroller should be removed.
Jumpers
There are four jumpers to configure the board as Master or Slave. The 5 possible configurations are:
| Type | CS Pin |
|---|---|
| Master | 10 |
| Slave 1 | 6 |
| Slave 2 | 7 |
| Slave 3 | 8 |
| Slave 4 | 9 |
- Master
- Slave 1
- Slave 2
- Slave 3
- Slave 4
