The E290 Shield is an add-on board designed for the Heltec Vision Master E290. This shield provides a convenient and modular solution for integrating additional functionalities such as GPS, a buzzer, and a vibration motor. It also exposes pins for easy soldering of additional components, making it highly versatile for various projects.

Key Features

  • GPS Control: The GPS module is controlled via a MOSFET, allowing for power-saving and easy toggling through firmware.
  • Buzzer Control: A transistor protects the board's GPIO pins while ensuring the buzzer operates at a high volume.
  • Vibration Motor Control: Similar to the buzzer, the vibration motor is controlled by a transistor, safeguarding the GPIO pins and providing strong feedback.
  • Battery Compatibility: The shield is designed to accommodate a 3000mAh battery, which can be sandwiched between the shield and the main board.
  • Expandability: Exposed pins allow for the addition of custom components, enhancing the shield's functionality.

Hi, I just received my E290 shield PCB's.
I flashed the Preview 2.6 HUD FW from the web flasher.
Is there a way to use the buzzer and the vibra motor? I don't see that they are separately configurable?

Is the issue that you can't see the "external notification" section in the app?

#

There was a small bug with the firmware in the preview which caused the external notification settings to be hidden in the apps. I think it got fixed in time for the 2.6.1 alpha which has just appeared in the web flasher

All good! I'm not sure exactly why it helped, but hey the important thing is that it's working

Any plans for a case designed with this hardware configuration in mind? (E290 +Shield+ battery)

#

yeah I'm going to soon

Now after

modified it to wrap around the battery so that it doesn't make the case any thicker than it already is. Also using the ATGN336H GPS module cause it's much smaller.
