SL-ADP-PCIe-M2 M.2 PCIe mass storage adapter Datasheet and Pinout
General description
SL-ADP-PCIe-M2 is adapter dedicated to using M.2 mass storage (SSD, single lane) in embedded systems based on i.MX8Mmini MPU. The SL-ADP-PCIe-M2 module is equipped with M.2 key M connector and is compatible with 2242, 2260 or 2280 modules.
The SL-ADP-PCIe-M2 module is equipped with FPC16 connector - the same like in SoMLabs carrier board VisionCB-8M-STD.
Features
- Equipped with M.2 key M SSD socket
- Single rail +3.3V power supply
- Single lane PCIe communication interface
- Operating temperature -30÷+85°C
- Fully compatible with SoMLabs carrier boards equippped with PCIe interface on FPC16 connector
- Built-in 32kHz clock source
- Built-in two LEDs
- Compatible with 2242, 2260 and 2280 modules
- Connection with carrier board using FPC16 cable
