Winner Micro W600 Series (Wi‑Fi Chips)

Winner Micro's W600 series of Wi-Fi chips (the W600 and W601) provide wireless connectivity through 2.4 GHz Wi-Fi (IEEE 802.11b/g/n) and are based around an Arm Cortex-M3 32-bit processor core. The W600 system-on-chip gained attention in the maker/electronics community in late 2018 due to its use in Luat's low-cost Air602 Wi-Fi module and the EVB_W602_A11 development board.

“Modules” in this context refer to “production ready” modules that are designed with the intent of being incorporated into a final device, and thus do not have on-board components which would likely be superfluous in a final product. For example, in contrast to a “development board”, these modules typically have no on-board USB-to-UART interface chip (nor associated USB connector), nor programming buttons for flashing & reset. ↑
“Development boards” in this context refer to printed circuit boards intended for use in evaluating, prototyping, and otherwise developing a device. These boards have on-board components which aid in the process of device development; for example, on-board USB-to-UART, USB connector, and physical buttons for programming (flashing and resetting) purposes. ↑
