Ebyte Offers Low Cost Wireless Modules for LoRa, Zigbee, NB-IoT, Bluetooth, and More

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.

You’ll find more details including an 18-page user manual in the product page. This module is sold for $9.06 on eBay,  and $9.49 on Aliexpress.

Ebyte ME3612 NB-IoT wireless module.

    • Download: 34Kbps; upload: 66Kbps
    • Bands:

      • B5  824 ~ 849MHz (TX), 869 ~ 894MHz (TX)
      • B8  880 ~ 915MHz (TX), 925 ~ 960MHz (TX)
    • SIM/USIM card compatible;
    • 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.
