Product detailed description
Transmitter module for PT100 and PT1000 platinum temperature sensors with SPI interface. Thanks to the MAX31865 chip, highly accurate measurement results are achieved for both four-wire and three-wire PTC sensors. The converter also supports two-wire sensors. However, these cannot be expected to be as accurate as multi-wire sensors.
The module is supplied in a configuration for the use of PTC sensors type PT100. If it is necessary to use a module with a PT1000 type sensor, it is necessary to cut and connect jumpers JP1 and JP3 from the other side.
Setting the number of wires:
- 4 wire sensors: JP2 and JP5 disconnected, JP4 connected at the top (default)
- 3 wire sensors: JP2 disconnected, JP5 connected, JP4 connected down
- 2 wire sensors: JP2 and JP5 connected, JP4 connected on top
Specifications:
- Chip used: MAX31865
- Support: temperature sensor type PT100, PT1000 - 2, 3, 4 wires (setup via JP1-5)
- Power supply: 3.3V
- Interface: SPI
- Accuracy: 0.5°C, full range 0.05%
- ADC resolution: 15-bit
- Temperature resolution: 0.03125°C

výkres zapojení - chyba
Jaromír
Dobrý den,
v HW výkresu zapojení je chyba - klema JP1 je na R4 - ve skutečnosti na desce je na R3

Good quality. Was easier to solder/cut than the adafruit alternative. Works successfully with the same library. The resistor and readings were accurate. The SPI pins are different so it is not a drop in replacement, the other board's SPI pins line up better with the hardware SPI pins, so you can solder straight lines. If you are starting from scratch this is probably better.
