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 |
