Bidamos 007s - Wemos PRO replacement with external antenna.

We have used Wemos PRO a lot. So, when some time boards available on market have shown many problems (not working I2C, bad WiFi range when on external antena) we have decided to build own module.

To make it simple we have based it on ESP07s from AiThinker. This module has 4MB of flash, but we have never used 16 MB from Wemos PRO and by default use external antenna (no need to solder jumpers to use) - for our need it is good replacement and we never had encounter problems with ESP07s quality.

We have placed it on board in Wemos form format allowing use Bidamos 007s as direct replacement for most projects. We have skipped USB/Serial converter since we don’t use them much in our projects.

Specification:

• Procesor: ESP8266 (based on ESP07s) with default firmware from AiThinker
• No antenna, U.FL connector
• Built in 3.3V regulator with 500 mA max output, but remember that according to ESP07s specs it can use up to 500mA of current

Set includes:

• Module Bidamos 007s

No goldpins, no pigtails nor antennas
