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.
Electrical characteristics & level shifting
- Logic levels are commonly TTL (5V) or 3.3V TTL. Supplying VCC at 5V while connecting 3.3V logic directly to TX/RX risks damage—use level shifters if needed.
- If the module provides a 3.3V output, it can often power low-current 3.3V devices (check current rating).
- Ground must be common between module and connected device.
Recommended next steps
- Locate the official datasheet or schematic for your exact e07-m1101d revision and confirm pin labels.
- Measure voltages on VCC/TX/RX before connecting external devices.
- Use a logic-level converter when interfacing mixed-voltage systems.
- If programming a microcontroller, search for community notes about which control pin (DTR/RTS) performs auto-reset.
If you want, I can:
- produce a concise wiring diagram for a specific microcontroller (specify model), or
- search and extract the official pinout/schematic for your exact e07-m1101d revision.
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

Pin 1 is at the corner near the antenna pad (check your vendor’s marking). Logic levels are commonly TTL (5V) or 3
