2x4 pin layout
The E07-M1101D is a popular, low-cost transceiver based on the Texas Instruments CC1101 chip. While it's highly stable and great for smart home or industrial applications, "Version 2.0" of these modules often shifts from a 2x5 pin layout to a , leaving many makers scratching their heads. e07-m1101d pinout
Symptom
: SPI bus conflicts if other devices share MOSI/MISO/SCK. Fix : Drive CSn from an MCU pin. Never ground it permanently unless the e07-m1101d is the only SPI device. Review: e07-m1101d pinout | e07-m1101d Pin | Arduino

2.0mm pitch
The module typically uses a spacing (double check your specific PCB footprint, as some EBYTE modules vary between 1.27mm and 2.0mm).
