LTE Cat 1 Pi HAT (USA - AT&T)
- 10+: $66.00
- 20+: $64.00
Seeed’s LTE CAT.1 Pi HAT is an open source cellular extension modem for Raspberry Pi, based on u-blox LARA-R2xx series. It compatible with Raspberry Pi 1 Model B+ and later versions.
LTE CAT.1 Pi HAT is designed for LTE Category 1 networks and with 2G fallback(EU version only). Embedding common protocols, like TCP/UDP, HTTP.
LTE CAT.1 Pi HAT support UART and USB interfaces. By UART, Raspberry Pi communicate with LTE CAT.1 Pi HAT via AT command without any special driver. It’s well suited for building prototyping rapidly.

Face Recognization Smart Lock with LTE Pi HAT
In this project, we plan to take pictures with picamera and recognise faces in them, then display recognition result in the screen. If faces known, open the door, and send who opened the door to specified phone number via SMS.

Which model will work on US T-Mobile bands? The R202 shows it supports bands 2,4,5, & 12 -- all of which T-Mobile supports. The R203 drops band 5. T-Mobile also supports 66 and 71, so I imagine it's maybe a coverage issue only? Or is there more to it than that?Question by: admin on 2018-12-18 02:24:16
Hi there, we can see from datasheet **https://github.com/SeeedDocument/LTE_Cat_1_Pi_HAT/raw/master/res/LARA-R2_DataSheet_(UBX-16005783).pdf** that the r202 not only supports LTE bands 2,4,5,12, but also support UMTS bands 850, 1900. R203 only supports LTE bands 2,4,12. thanks.Answer by: admin on 2018-12-18 02:24:16
I just received the LTE CAT.1 Pi HAT (LARA-R203 AT&T) and it doesn’t seem to communicate via USB. The device doesn’t enumerate as seen using lsusb or generate any messages on dmesg when plugged in. From the description, it sounds as if the LTE CAT.1 can use the USB interface to act as a USB LTE modem. Is this the case? If so maybe my unit is faulty? If this device can only use the UART for data transmission would this not be an unnecessary bottleneck for a high speed LTE modem?Question by: admin on 2018-12-18 02:24:04
Hi there, I use raspberry pi and it can detect the device. **pi@raspberrypi:~ $ lsusb Bus 001 Device 005: ID 1546:110a U-Blox AG**. We also can use the windows to detect. **http://wiki.seeedstudio.com/LTE_Cat_1_Pi_HAT/#faq**. If you can not detect the device, do you use a 4 wire usb cable? can the cable transfer data, please? thanks.Answer by: admin on 2018-12-18 02:24:04
