GHI Electronics,LLC Embedded Master User Manual
Embedded Master design Consideration
4. Embedded Master Design Consideration
4.1. Hardware
The following peripherals are recommended to be exposed from the module in any design,
possibly hidden from the end user:
• UART0 (COM1) pins. (Updating TinyBooter/Firmware)
• UP, Down and Select Buttons pins. (Selecting the BootLoader)
• USB Device (Client) if it is used for debugging or TinyBooter communications
4.2. Software
Embedded Master Module is usually shipped with GHI Bootloader and Tinybooter only.
The firmware has to be downloaded through USB using Microsoft MFDeploy tool.
If the user is using in-field firmware update feature (without USB), it would a good idea to
have this USB port exposed in case of firmware update failure, for example a power loss.
4.3. Embedded Master Placement
Embedded Master Module was designed to be easily placed and soldered, machined or
manually. This image shows a manually-soldered module. Static sensitive precautions
should take place when handling the modules.
