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'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'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's logic level before use.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- RTC
- A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
