Which HAT / Shield should I use on Raspberry pi model 4B?
For a 4G setup you will need
- Raspberry Pi 3G-4G/LTE Base HAT
- Quectel EC25 Mini PCle 4G/LTE Module. Variant according to your location.
- LTE Antenna according to your use, such as:
- LTE Main & Diversity Dual u.FL Antenna – 100mm LTE connection only.
- LTE Full Band PCB Antenna – u.FL Plug – 100mm LTE connection only.
- LTE Main & Diversity & GNSS Triple Port u.FL Antenna – 100mm If you want GPS Data too.
There are also different LTE antennas (You can check them from https://sixfab.com/product-category/antennas/ )
You can also have GPS antenna separately GNSS.
We have tutorials available on our website. (PPP installer and QMI interface are enough for 4G connectivity.)
The Quectel EC25 module supports FTP too.
