These are community-contributed "common" boards or components distributed with tscircuit

import { ArduinoShield } from "tscircuit/common"

return (
  <ArduinoShield
    chipProps={{ connections: { GND1: "net.GND" } }}
    boardProps={{ solderMaskColor: "blue", autorouter: "auto" }}
  >
    {/* ... */}
  </ArduinoShield>
)

The RP2040 subcircuit includes the microcontroller, QSPI flash, crystal, USB-C, power regulation, decoupling, boot/run controls, and SWD test points:

import { Microcontroller_RP2040 } from "@tscircuit/common"

return <Microcontroller_RP2040 name="MCU" pcbX={0} pcbY={0} />

The MT3608 power-boost subcircuit includes its battery connector, cutoff MOSFET, USB-present shutdown, boost converter, feedback divider, and input/output filtering. Place the power switch on the parent board between BAT_POS and BAT_SWITCHED, or connect them to the same net for always-on operation:

import { PowerBoost_MT3608 } from "@tscircuit/common"

return (
  <>
    <PowerBoost_MT3608
      name="POWER"
      exposedNets={["BAT_POS", "BAT_SWITCHED", "VBUS", "VSYS", "GND"]}
    />
    <trace from="net.BAT_POS" to="net.BAT_SWITCHED" />
  </>
)

The trace above configures the battery input as always on. Replace it with a switch between BAT_POS and BAT_SWITCHED when switched operation is needed.

The Game Boy PAM8403 3 W audio-amplifier subcircuit includes the PWM input filter, input coupling, amplifier decoupling, speaker EMI filter, and speaker connector:

import { AudioAmplifier3W_PAM8403 } from "@tscircuit/common"

return (
  <AudioAmplifier3W_PAM8403
    name="AUDIO"
    exposedNets={["AUDIO_PWM", "V3V3", "VSYS", "GND"]}
  />
)

Internal nets remain private by default. Use exposedNets to expose a selected set, or exposeNets when every internal net should be exposed.
