Other documents, such as the TLSR9118 datasheet, hardware guidelines, and AIOT-DK2 board files (schematics and PCB layout), are also available, but only through a Telink FAE or sales representative.
The Telink ML9118A module and development board appear to be available now, but I could not find price information. Check out the product page and the press release for more information.
Thanks to TLS for the tip.
