Poblano 43C Single-Board Computer

The Poblano 43C improves upon the Pepper 43C SBC by incorporating TI's beefier AM4378 processor (vs. TI AM335x). It also contributes 8 GB embedded NAND Flash storage to the Pepper design.

Like the Pepper 43C, the Poblano is compatible with the Newhaven 4.3" capacitive multi-touch LCD touchscreen and provides audio I/O, WiFi, BLE and USB OTG making for a powerful handheld development platform.

The connector for Newhaven Capacitive Multi-Touch Screens is ideal for providing a user interface for handheld devices needing multi-touch graphical input with audio for industrial, medical, and automation systems.

It also includes:

  • Connector for Caspa family of cameras
  • Gigabit Ethernet
  • 20-pin GPIO
  • RTC

Customize Your Board

Customize the Poblano 43C to your project's specific needs in Geppetto D2O. Add functionality or remove unused components with the ease of a drag-and-drop interface.
