+## Xiao + Expansion board + BME680
+
+The generic sample above can be specialized to run on a Xiao ESP32-C3 with expansion board.
+
+```ts
+import {
+    XiaoExpansionBoard,
+    startCharacterScreen,
+    startBME680,
+} from "@devicescript/drivers"
+import { ValueDashboard } from "@devicescript/runtime"
+
+const board = new XiaoExpansionBoard()
+const { temperature, humidity } = await startBME680({
+    address: 0x76
+})
+const display = await board.startDisplay()
+const screen = await startCharacterScreen(display)
+
+const dashboard = new ValueDashboard(screen, {
+    temperature: { digits: 1, unit: "C" },
+    humi: { digits: 0, unit: "%" },
+})
+
+setInterval(async () => {
+    dashboard.values.temperature = await temperature.reading.read()
+    dashboard.values.humi = await humidity.reading.read()
+    await dashboard.show()
+}, 1000)
