Description

JB-MEGA32 V1.1 development kit with ATMEGA32 and RTC

The JB-MEGA32 V1.1 development kit is a great base for your own projects and for educational purposes.

The kit can be used, for example, as a controller to drive the 8x8 LED matrix modules of the JB-LED BiCOLOR v1.1 display, the design of which I also shared.

Mounting: SMT, THT

Number of layers: 2

Kit features:

- ATmega32A-AU (TQFP-44) microcontroller

- DS1307Z+ or DS3231MZ RTC (interchangeably not together)

- Battery compartment for RTC backup

- Space for external EEPROM (I2C) memory

- Expandable with other custom modules or prototyping boards (angle connectors on the side of the board)

- Standard 6-PIN ISP connector for programming

- 5VDC regulator (7~12VDC power supply - 7~9VDC recommended - or better 5VDC directly via ISP)

- PCB dimensions: 34.6x78mm
