AVT5171 B

cButton is a device emulating popular Maxim-Dallas pills used as electronic keys that open various types of "locks". It can be an electronic safe, immobilizer or other type of security. The author of the project using a lot of this type of "keys" came up with the idea of building a system that allows making copies of keys and saving them in the microcontroller's memory, and then switching between them.

Basic parameters:

• Fuse-bit settings: CKSEL3 ... 0 = 0100, SUT1 ... 0 = 01
• Dimensions of the printed circuit board: 91 × 39 mm
• Supply voltage: 9 V
• Maximum supply current: 70 mA (depends on the supply current of the LCD backlight)
• Number of emulated circuits: 10
• Supported 1-Wire bus orders: 33h, 0Fh
• Maximum transmission speed: 16.3 kbps
• The set includes a printed circuit board, a set of elements and documentation.
