It can be programmed using the Arduino IDE with Teensyduino add-on. Teensy 4.0 is the same size and shape as Teensy 3.2, and retains compatibility with most of the pin functions on Teensy 3.2.Item SpecificsARM Cortex-M7 at 600 MHz1024K RAM (512K is tightly coupled)1984K Flash, 1024K RAM (512K tightly coupled), 1K EEPROM (emulated)2 USB ports, both 480 MBit/sec3 CAN Bus (1 with CAN FD)2 I2S/TDM Digital Audio1 S/PDIF Digital Audio1 SDIO (4 bit) native SD3 SPI, all with 16 word FIFO3 I2C, all with 4 byte FIFO7 Serial, all with 4 byte FIFO32 general purpose DMA channels31 PWM pins40 digital pins, all interrrupt capable14 analog pins, 2 ADCs on chipCryptographic AccelerationRandom Number GeneratorRTC for date/timeProgrammable FlexIOPixel Processing PipelinePeripheral cross triggeringPower On/Off managementLockable Review: Incredible Dev Board - Worked perfectly for reverting the fw on my ps4 fat. Fantastic teensy! Review: It’s a good board, but not what I needed - This is a good board if it meets your needs. I had used a Teensy 2 before, so it seemed like a newer Teensy would be the way to go. I didn’t look closely enough to see that this board doesn’t support 5V inputs and that it isn’t well supported (if at all) for QMK firmware. Perhaps I will find a use for it in the future, though. ## Features - Lockable for secure device development - Version 4.0 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CVSC7MPT | | Best Sellers Rank | #3,802 in Single Board Computers (Computers & Accessories) | | Brand | PJRC | | Built-In Media | Teensy 4.0 Lockable Development Board | | CPU Model | Core M Family | | CPU Speed | 0.6 GHz | | Compatible Devices | Arduino Boards, Computers (PCs, laptops, tablets), Smartphones | | Connectivity Technology | USB | | Customer Reviews | 4.8 out of 5 stars 6 Reviews | | Item Dimensions L x W x H | 4"L x 0.1"W x 6"H | | Item Weight | 1 g | | Manufacturer | PJRC | | Memory Storage Capacity | 1.02 MB | | Model Name | Teensy 4.0 | | Operating System | Arduino | | Processor Brand | ARM | | Processor Count | 1 | | Processor Speed | 0.6 GHz | | RAM Memory Installed | 1024 MB | | RAM Memory Technology | LPDDR4 | | Ram Memory Installed Size | 1024 MB | | Total Usb Ports | 2 | | UPC | 724376599363 | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** PJRC - **CPU Model:** Core M Family - **Memory Storage Capacity:** 1.02 MB - **Model Name:** Teensy 4.0 - **Ram Memory Installed Size:** 1024 MB ## Images ![PJRC Teensy 4.0 Lockable Development Board - Image 1](https://m.media-amazon.com/images/I/61iRdxkqWQL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Incredible Dev Board *by C***E on July 6, 2025* Worked perfectly for reverting the fw on my ps4 fat.
