[Introduction]：E15-PCIE-T1 wireless module adapter board is a test board developed by Chengdu Ebyte for the mini PCI-e interface LoRa wireless module. The PCIE adapter board is mainly aimed at the embedded application of the E22 series LoRa modules launched by our company. , and equipped with ESD protection, supporting multiple systems and multiple baud rates. Developers can easily connect a variety of peripheral devices through jumpers according to actual needs.
| Pin number | Pin name | Type | Pin usage |
| 1 | GND | - | Power reference ground |
| 2 | +5V | - | Power input 5.0V |
| 3 | SWC | input /Output | Program download clock interface (the module needs to be reset or fully erased before SWD burning) |
| 4 | SWD | input /Output | Program download data interface (the module needs to be reset or fully erased before SWD burning) |
| 5 | M1 | Input (very weak pull-up) | Cooperate with M0 to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used) |
| 6 | GND | - | Power reference ground |
| 7 | M0 | Input (very weak pull-up) | Cooperate with MI to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used) |
| 8 | GND | - | Power reference ground |
| 9 | AUX | Output | Used to indicate the working status of the module. The user wakes up the external M0 and outputs it during power-on self-test initialization. Low level: (can be left floating) |
| 10 | RXD | input | TTL serial port input, connected to external TXD output pin |
| 11 | TXD | Output | TTL serial port output, connected to external RXD input pin |
| 12 | +5V | - | Power input 5.0V |
| 13 | GND | - | Power reference ground |
