E07-m1101d Pinout [extra Quality]

Review: e07-m1101d pinout

Mistake 4: No Decoupling Capacitor

Symptom: Unstable transmission, reduced range, or occasional resets when turning on a motor nearby.
Fix: Add a 10 µF tantalum or ceramic capacitor + 100 nF ceramic directly across VCC and GND.

Recommended next steps

  1. Locate the official datasheet or schematic for your exact e07-m1101d revision and confirm pin labels.
  2. Measure voltages on VCC/TX/RX before connecting external devices.
  3. Use a logic-level converter when interfacing mixed-voltage systems.
  4. If programming a microcontroller, search for community notes about which control pin (DTR/RTS) performs auto-reset.

If you want, I can:

I have written this based on the standard E07-M1101D (an 868/915 MHz SMD wireless module from Chengdu Ebyte). Note: If you meant a different variant (e.g., E07-M1101D-TH), the pinout may differ slightly. e07-m1101d pinout
