Chengdu Ebyte Electronic Technology Ltd (or just Ebyte for short) is a company based in Western China that design and manufacturer low cost wireless modules for LoRa, WiFi, Bluetooth, Zigbee, NB-IoT & GPRS cellular connectivity, many of which appear to be FCC certified.
The list of modules is way too long, so I’ll just have a look at two products from the company: Ebyte E32-915T20D LoRa 915 MHz module and Ebyte ME3612 NB-IoT wireless module.

- Complies with 3GPP TS 27.007, 27.005 AT command
- Supply Voltage – 3.4V ~ 4.2V (typical 3.8V)
- Low power modes – PSM, EDRX
- Dimensions – 30 x 30 x 2.3mm; 80-pin LCC package
I could not find a product page on the official website, but a ZIP file includes all documentation mostly in Chinese, but also in English, as well as Windows based tools (e.g. ZTE Log Catching Tools ) and drivers.
The module does not appear to be particularly inexpensive however, as it is sold for $39.69 on eBay. There’s no such Ebyte module on Aliexpress, but interestingly the exact same module is sold under another brand (Gosuncn) for just $17.14 shipped.
You’ll find more modules with pricing on Ebyte stores on eBay and Aliexpress.
