Note Seeed fusion offers PCB/ PCBA manufacturing service for customized products based on W600 Module with an online instant quote and fast delivery. Furthermore, business users can enjoy a free prototype and engineer support as well. Click here to learn more! The W600 Module is a cost-effective 2.4GHz WiFi module support 802.11b/g/n. Seeed W600 Module is based on the W600 chip which features ARM Cortex-M3 with 1MB on-chip flash and freeRTOS kernel. We take the pins of the W600 chip out and put them on the back of the board, including I2S/I2C/SPI/GPIO. In addition, this module has an onboard PCB Antenna, no need to design the antenna separately, so you can quickly deploy the module to your own board. We also have made CE/FCC certification for this module and you can use it directly for business projects. What's more, for Arduino user we also released the Grove - W600 which is built around this module. The Grove - W600 makes it so convenient and cost-effective for makers to add WiFi function to Arduino compatible systems. We really think the W600 is a cost-effect and powerful WiFi chip, and we seriously consider it as an ESP8266 competitor. So we made this module and hope it may impress you.
