| Parameter | Value |
|---|---|
| Type | Power supply / breadboard integration board |
| Interface | Direct pin passthrough |
| Power Input | USB-C (via XIAO) or external |
| Voltage Output | 3.3V and 5V regulated rails |
| Dimensions | Not available |
All Seeed Studio XIAO form-factor boards (standard XIAO pinout).
XIAO Pin | Accessory Function | Protocol
------------|--------------------------|----------
All pins | Passthrough to breadboard | Direct
3V3 | 3.3V power rail | Power
5V | 5V power rail | Power
GND | Ground rail | Power
The PowerBread passes through all XIAO pins to breadboard-compatible rows. No pins are consumed by the board itself.
| Parameter | Value |
|---|---|
| Power Source | USB-C via XIAO or external power input |
| Output Rails | 3.3V and 5V regulated |
No libraries or special setup required. The PowerBread is a passive power/breakout board.
// No special code needed for PowerBread
// Simply use XIAO pins as normal — they are passed through to the breadboard
void setup() {
Serial.begin(115200);
pinMode(D0, OUTPUT); // Example: use any pin on the breadboard
}
void loop() {
digitalWrite(D0, HIGH);
delay(500);
digitalWrite(D0, LOW);
delay(500);
}
No special drivers or setup required. Use XIAO pins as normal.
package main
import (
"machine"
"time"
)
func main() {
led := machine.D0
led.Configure(machine.PinConfig{Mode: machine.PinOutput})
for {
led.High()
time.Sleep(500 * time.Millisecond)
led.Low()
time.Sleep(500 * time.Millisecond)
}
}
No communication protocol — the PowerBread is a passive passthrough board with power regulation.
