## Description

This passive adapter lets a Teensy development board connect to the standard Arduino 1.0 (R3) shield footprint, making it easier to reuse existing Arduino shields without a breadboard full of jumper wires.Solder your Teensy board, sold separately, to the marked footprint on the adapter, then plug compatible shields into the Arduino-style headers. The adapter itself needs no special programming; your Teensy just needs to be programmed for the shield you attach.The board also adds useful project hardware including power input options, an RTC coin cell holder, ICSP breakout, I2C jumpers and a DAC pin header. Documentation provided by the supplier includes a schematic, Eagle files, hookup guide and GitHub resources.Features:Flexible Power: Includes a 4-12V barrel jack and a 2-pin JST connector for powering your project from a wall adapter or a LiPo battery.Real-Time Clock (RTC): Coin cell battery holder is included to power the Teensy&#39;s RTC; battery not included.ICSP Header: ICSP header is broken out for shields that use it for SPI communication.Arduino R3 Interface: Breaks out the Teensy&#39;s pins to the standard Arduino 1.0 (R3) layout.Real Time Clock Battery: Supports an RTC backup battery holder for compatible Teensy boards.JST Battery Connector: Includes a JST battery connector.Barrel Jack: Includes a barrel jack power input.I2C Jumpers: Includes I2C jumpers.ICSP Header: Includes an ICSP header.DAC Pin Header: Includes a DAC pin header.Specifications:Adapter type: Passive adapter.Arduino shield layout: Standard Arduino 1.0 (R3) footprint.Barrel jack input: 4-12V.Battery connector: 2-pin JST connector.RTC battery: Coin cell battery holder included; battery not included.Logic level: Teensy is a 3.3V device.Shield compatibility: For 3.3V-compatible shields.5V shield warning: May be incompatible with older, 5V-only Arduino shields.5V damage warning: Using a 5V shield can permanently damage your Teensy.Teensy LC compatibility: Adapter footprint fits the Teensy LC.Teensy LC limitation: Not all adapter features, like the RTC, are compatible with the Teensy LC.Teensy 3.1 compatibility: Designed to fully utilise the features of the Teensy 3.1.Teensy 4.0 compatibility: Not compatible with the Teensy 4.0 due to differences in the pin layout.Assembly: Basic soldering is required to assemble this kit.Best suited to makers upgrading Arduino shield-based projects to a compatible Teensy controller. Check your shield&#39;s logic level before use.

**Product Type:** Shield Adapter
