1. Overview FLOWERMCU is a dual-core microcontroller unit with Wi-Fi and Bluetooth Low Energy capabilities using the devices integrated trace antenna. The FLOWERMCU is intended to be used for wearable devices but only using Bluetooth Low Energy (Wi-Fi must be disabled for use in wearable devices through a software lock). The FLOWERMCU can operate at different clock rates between 80 MHz to 240 MHz to allow for reduced power consumption.
2.2 Schematics and PCB Landings There is no difference between the FLOWERMCU and the ESP32-WROOM-32D in respect to the schematics and PCB landing patterns since it is the same module. The required information can be found on Espressif’s website. Schematics PCB Landing Patterns 2.3 Physical Appearance Since the FLOWERMCU is a rebranded ESP32-WROOM-32D, the external appearance is changed to reflect the rebranding along with the different FCC ID for the FLOWERMCU.
3. Use Cases The primary use case of the FLOWERMCU is for wearable electronics that require Bluetooth Low Energy connectivity along with a microcontroller unit. The FLOWERMCU should not and cannot be used for portable devices/wearables if Wi-Fi connectivity is needed for its normal functionality. 3.1 Acceptable Use of Bluetooth and Wi-Fi for Portable Use The FLOWERMCU can operate using Bluetooth Low Energy connectivity when integrated into products designed for portable use.
