CJMCU-1293 - How to connect?

Hello everybody,

I have CJMCU-1293 (1pcs CJMCU 1293 ADS1293 Electrocardiogram Physiological Signal Measurement Module 3 Channel 24 Bit Analog Front End Module|Integrated Circuits| - AliExpress). I would like to connect it to my LOLIN32. The 3.3V should work but I do not know how to connect it because some of the CJMCU-1293 pins has "weird" SPI label.

The CJMCU-1293 pins:

  1. +5V
  2. GND
  3. SCLK
  4. SDI
  5. SDO
  6. CSB
  7. WCT
  8. ALAB
  9. DRDB

The LOLIN32 SPI pins:
GPIO19 - MISO
GPIO23 - MOSI
GPIO18 - SCK
GPIO5 - SS

The CJMCU-1293 pin #1 +5V should be connected to 3V3.
The CJMCU-1293 pin #2 GND should be connected to GND.
The CJMCU-1293 pin #3 SCLK should be connected to GPIO18 - SCK.
The CJMCU-1293 pin #4 SDI should be connected to GPIO23 - MOSI.
The CJMCU-1293 pin #5 SDO should be connected to GPIO19 - MISO.
The CJMCU-1293 pin #6 CSB should be connected to GPIO5 - SS.
The CJMCU-1293 pin #7 WCT should be connected to ???
The CJMCU-1293 pin #8 ALAB should be connected to ???
The CJMCU-1293 pin #9 DRDB should be connected to ???

Is the connection correct? Does anyone know where to connect ALAB (which should be alarm signal) and DRDB (which should be data ready signal)?

I found only this library (GitHub - Protocentral/protocentral-ads1293-arduino) for Arduino. Will it work even when my board is not Protocentral but CJMCU?

Thank you.
Alex.
