E07-m1101d Pinout Jun 2026

| Pin | Name | Type | Description | |-----|-------------|-----------|-----------------------------------------------------------------------------| | 1 | ANT | RF I/O | Antenna port (50 Ω). Connect directly or via a matching network. | | 2 | GND | Power | Ground – must be connected to system ground plane. | | 3 | 3.3V | Power | Main supply (2.2 V – 3.6 V, typical 3.3 V). Requires 100 mA peak current. | | 4 | RST | Input | Active-low reset. Pull to GND to reset, then float or pull high. | | 5 | SCK | Input | SPI clock (max 10 MHz). Idle low, data sampled on rising edge. | | 6 | MISO | Output | SPI Master-In Slave-Out. Tri-stated when not selected. | | 7 | MOSI | Input | SPI Master-Out Slave-In. Sampled on clock rise. | | 8 | NSS | Input | SPI chip select (active low). Must be low for SPI communication. | | 9 | BUSY | Output | Busy indicator. High when module is processing (cannot accept commands). | | 10 | DIO0 | I/O | Digital I/O – configurable interrupt (e.g., TxDone, RxDone, CAD detected). | | 11 | DIO1 | I/O | Second interrupt line (e.g., FhssChangeChannel, RxTimeout). | | 12 | NC / GND | – / Power | No connect internally – but often PCB tied to GND. Check your vendor. |

The e07-m1101d uses a edge connector with a 2.0 mm pitch . Pins are numbered from 1 to 12, typically with pin 1 indicated by a dot or chamfered corner on the PCB. e07-m1101d pinout
