W600-PICO | A W600-Based Board Running MicroPython for Only $2?

We first met the WinnerMicro W600 back in late 2018 when Seeed Studio released their Air602 WiFi Module. Three more boards from Seeed followed, along with yet another board that used the Feather form factor. But none of them really let you get your hands dirty with the W600 directly.

W600 could well be a competitor for the ESP8266, the chip has proved somewhat of a disappointment. Unlike the ESP8266, which was quickly picked up by the community, the W600 has stayed as designed—and has been used only as a Wi-Fi-to-Serial bridge—at least, until now.

New W600-PICO from Wemos, which comes pre-loaded with a MicroPython firmware onboard and Wemos has set-up a Wiki for the board explaining how to flash the board, and get started with networking, I/Os, RTC, and timers. Users who purchased the board on Aliexpress appear to be satisfied, and one mentions “Micropython works immediately”. Checkout this for Get started with MicroPython [W600 series].
