Microcontroller module Chip45 AVRCrumb128
Crumb128 V4.0 is a versatile, very small (just 40×30mm footprint!) microcontroller module with the ATmega128 or AT90CAN128 with CAN transceiver or ATmega2561 microcontroller, a CP2102 USB UART converter and a RS485 transceiver.
Detailed Description
All MCU signals are available on pads. A watch crystal (TOSC) is preassembled and a selectable XTAL crystal is included.
The Crumb128 is being shipped without preassembled pinheaders, since everybody has different preferences here. A suitable Connector Kit with pin headers and receptacles can be ordered optionally.
Features:
- ATmega128 (128k Flash, 4k SRAM, 4k EEPROM)
- Interfaces: 2×UART, SPI, TWI (I2C), ext. processor bus
- ISP interface with 6-pin standard pinout
- CP2102 USB UART converter at UART0
- SN75ALS176 RS485 transceiver at UART1
- optionally: AT90CAN128 MCU with PCA82C251 CAN transceiver onboard or ATmega2561
- 32768Hz watch crystal preassembled
- XTAL crystal frequency selectable
- connections: 2×32-pin with all processor signals, 1× 8-pin with USB and RS232 signals, 1× 6-pin ISP
- 2.54mm (1/10inch) modular grid
- dimensions: 40.64mm × 30.48mm
Other Names:
AVRCRUMB128, AVR CRUMB128
