E07-m1101d Pinout -

The module communicates via a 4-wire SPI interface and provides two universal digital output pins (GDO pins) for flexible functions like wake-on-radio or signal assessment. Description Typical Arduino Connection Power ground connection 1.8V to 3.6V only; exceeding 3.6V will damage it General Purpose Digital I/O 0 Digital Pin 2 SPI Chip Select (Low active) Digital Pin 10 SPI Clock input Digital Pin 13 SPI Master Out Slave In Digital Pin 11 SPI Master In Slave Out Digital Pin 12 General Purpose Digital I/O 2 Optional / Not wired Key Performance Specifications Frequency Range:

: Some e07-m1101d modules have an 11th pin (labeled “GND”) at the bottom center for mechanical stability and improved grounding. Electrically, it is identical to pins 1 and 10.

387MHz to 464MHz (Standard 433MHz band) Transmission Power: Max 10mW (+10dBm), software-adjustable e07-m1101d pinout

She traced the trace (no pun intended) back to a massive transformer. "High voltage input. Don't touch that."

: Download Ebyte’s configuration software (RF_Setting.exe), experiment with GDO2 as an interrupt for packet reception, and explore the module’s wake-on-radio capabilities for battery-powered projects. The module communicates via a 4-wire SPI interface

Up to 1000m (line-of-sight with high-quality antenna) Interface: SPI Critical Usage Notes

| Symptom | Likely Cause | Fix | |-----------------------------|---------------------------------------|--------------------------------------| | No SPI response (MISO stuck)| NSS not pulled low; BUSY ignored | Assert NSS low; wait for BUSY=0 | | Module resets randomly | Insufficient 3.3V decoupling | Add 100 µF bulk cap near pin 3 | | No RF output | Antenna not connected / wrong pinout | Check pin 1 connection; add matching | | Erratic DIO0 interrupts | Floating interrupt line | Enable internal pull‑down or external 10 kΩ | | Overheating | 5 V applied to any pin (even briefly) | Replace module; use level shifter | 387MHz to 464MHz (Standard 433MHz band) Transmission Power:
