AI Overview
Core boards (Teensy 4.1)
- Teensy 4.1 ($56.95) — 600MHz ARM Cortex‑M7 (NXP iMXRT1062) dev board; best default pick if you want the full Teensy 4.1 feature set.
- Teensy 4.1 (Headers) ($64.95) — same board but comes with headers pre-included for easier breadboard/prototyping.
- Teensy 4.1 without Ethernet ($54.30) or Teensy 4.1 without Ethernet (Headers) ($60.70) — choose these if you don’t need wired Ethernet.
Production / code-protection variants
- Teensy 4.1 Lockable Microcontroller Board ($54.20) — lockable variant aimed at moving from prototype to production.
- Teensy 4.1 Lockable Without Ethernet ($50.95) — lockable + no Ethernet PHY.
Popular add-ons for Teensy 4.1
- Ethernet: Ethernet Kit for Teensy 4.1 ($7.15) or the more integrated Ethernet Adapter for Teensy 4.1 ($9.75). For the Ethernet header connection, add 2x3-pin 2mm PTH Header Pins and Socket for Teensy 4.1 Ethernet ($1.10).
- USB host: USB Host Cable for Teensy 4.1 and 3.6 ($4.95) — converts the Teensy’s USB host header to a USB‑A female port.
- Extra RAM: 8MB PSRAM Chip for Teensy 4.1 ($4.25) or 8MB PSRAM chip for Teensy 4.1 ($3.30) — adds 8MB PSRAM (solder-on) for memory-hungry projects.
Headers / shields / getting started
- Teensy Stackable Header Kit (Extended) ($3.95) — stackable headers sized for Teensy 4.1 / 3.6 / 3.5.

ESP-PSRAM64H Chip - 64 Mbit Serial Psuedo SRAM - 3.3V 133 MHz
·
The ESP-PSRAM64H is a 64 Mbit (8 MB) serial pseudo SRAM chip in a compact SOIC-8 package. It provides fast, unlimited read/write external memory for microcontrollers like the ESP32 and Teensy 4.1, which have dedicated PSRAM pads or memory-mapping support for seamless integration. Unlike flash or...
GD25Q16 - 2MB SPI Flash in 8-Pin SOIC package
·
These little chips are like miniature SSD drives for your electronics. When you don't need something with as much storage as a micro SD card, but an EEPROM is too small, SPI (or QSPI) Flash chips give you on-the-order-of megabytes, with little cost and complexity. We use these chips all the time ...
USB-C to Micro-USB Cable - Black
·
A USB-C to Micro-USB cable for connecting Micro-USB development boards and devices to modern USB-C laptops and chargers. Ideal for programming boards like the Raspberry Pi Pico, Teensy 4.1, Circuit Playground Express, DFRobot Beetle, Maker UNO, and other Micro-USB devices. Specifications Conne...
OctoWS2811 Adapter for Teensy 3.x & 4.x
·
Build large LED displays with a Teensy using this OctoWS2811 adapter board. It connects Teensy 3.2 through 4.1 boards to thousands of WS2811, WS2812 or NeoPixel-compatible LEDs, with support for driving up to eight strips in parallel via the high-speed OctoWS2811 Library.The adapter acts as an ac...
Teensy to Arduino R3 Shield Adapter
·
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...
