Teensy 4.1 Lockable USB Development Board (Without Pins)

Teensy 4.1 features the fastest microcontroller and an expanded set of powerful peripherals in a 2.4 by 0.7 inch form factor. It's designed to bring all general purpose I/O pins to breadboard friendly pads on the outside edges. Additionally, the bottom side of Teensy 4.1 has locations to solder 2 memory chips. While Standard and Lockable Teensy are identical hardware, the permanent fuse configuration differs. Only Lockable Teensy provides proper code security, and only when a key is written and secure mode is locked.Item SpecificsSize: 2.4" x 0.7"ARM Cortex-M7 processor at 600 MHzTo use the Ethernet port, a magjack and capacitor need to be connectedRecommended Accessories (not included): USB Cable, Pins 24x1 (2), 8MB PSRAM, USB Host Cable, Ethernet Kit
