DSerial Components
DSerial uses ICs that require very few components.
Symbol | Package | Description |
---|---|---|
MCU | LQFP-32 | Silicon Laboratories C8051F320 USB microcontroller |
ACCEL | E-8 | Analog Devices ADXL311 dual axis accelerometer |
MAX | TSSOP-16 | Texas Instruments MAX3221 Single-Channel RS-232 Line Driver/Receiver |
LED1, LED2 | 0805 | Status LEDs |
R1 | 0603 | 2kOhm resistor (not needed) |
R2 | 0603 | 1MOhm resistor (for ACCEL) |
R3, R4 | 0603 | current-limiting resistors (around 47Ohm) |
C1, C2, C3, C4, C5 | 0603 | 0.1uF ceramic capacitors |
C6 | 0603 | 0.1uF ceramic capacitor (decoupling cap for MCU) |
C7, C8, C9 | 0603 | 0.1uF ceramic capacitors (for ACCEL) |
DSerial provides the following connectors.
Symbol | Number of contacts | Description |
---|---|---|
USB | 6 | Mini USB connector |
RS232 | 3 | RS232 level UART |
IO1 | 12 | First IO connector |
IO2 | 12 | Second IO connector |
PROG | 4 | Programming connector (initial programming) |
SLOT | 17 | DS Slot connector |
There are also a couple of solder jumpers.
Symbol | Default | Description |
---|---|---|
PWR | Disabled | Enables USB powered mode |
INV | Disconnected | Connects MAX3221 serial line sense to P0.7 of C8051F320. This could be used to detect whether a serial port is connected. |
X, Y | Analog | Selects duty cycle or analog mode for the accelerometer |
