1. Introduction of ACCEL EASY BOARD
ACCEL EASY BOARD is a product designed by ATC to provide users with integrated facilities that are interconnected into a network through ATCBus. Accel easy board carries the KXTJ3-1057, ±2g / ±4g / ±8g / ±16g tri-axis digital accelerometer, by ROHM. This sensor utilizes an advanced acceleration sensing method, based on the differential capacitance. The integrated MEMS, produced with the proprietary ROHM technology. In addition, Accel easy board supports jumpers to select IC address, allowing users to choose the address to communicate with the IC.

3. Feature of Accel Easy Board
a. Module ATC-E18
Into provide convenience for users, on Accel Easy Board has integrated ATCBus sockets to provide users convenience when combining with other easy board in the network ATCBus.
With ATCBus users can connect Accel easy board to other Easy boards to implement applications: Shock detection, impact recognition, concussion detector,…
b. Power Supply
On Accel easy board is integrated IC TJ5205SF5-2.5 stable voltage at 2.5V and voltage supplied from 5V PIN of ATCBus.
c. Logic voltage selection
To communicate with external devices with logic 5V/3V, the board has a custom designed user interface with 3.3V/5V logic voltage for application. When manufacturing, the default logic voltage is 5V logic level
Accel easy board uses two-way communication voltage converter with 3 C1815 Transistors, which can communicate at 3.3V and 5V..
d. IC Address Selection
On Accel easy board is integrated with a jumper to select the device address. Help users to choose the address to communicate with the IC.
e. I2C
I2C: Through 2 PIN SDA and SCL ATCBus, KXTJ3-1057 can transmit and receive data from control device.
f. PIN I/O
Reserved: Pins Reserved of IC KXTJ3-1057, users please connect to GND.
Physical Interrupt: KXTJ3-1057 has threshold interrupt feature activated by registers. It allows KXTJ3-1057 to activate the interrupt when the acceleration operation exceeds the allowable threshold.
g. Combined with other easy board
With the integration of ATCBus on the user board can easily be combined with other devices in the ATCBus network.
