In a home full of smart devices, or in an office or makerspace with lots of networks, 2.4 GHz-only boards can struggle to stay connected. Moving up to a larger board with more radios usually costs you space, power and money.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSeeed Studio XIAO ESP32-C5\u003c\/strong\u003e fixes that without making your project bigger. It's the first board in the XIAO family with \u003cstrong\u003edual-band 2.4 GHz and 5 GHz Wi-Fi 6\u003c\/strong\u003e. It also has \u003cstrong\u003eBluetooth 5 (LE)\u003c\/strong\u003e and \u003cstrong\u003eIEEE 802.15.4\u003c\/strong\u003e for Zigbee and Thread, all on a 21 x 17.8 mm board. Inside is Espressif's ESP32-C5 with a 32-bit RISC-V core running at up to 240 MHz, plus \u003cstrong\u003e8 MB Flash and 8 MB PSRAM\u003c\/strong\u003e, which leaves plenty of room for your code and network stacks.\u003c\/p\u003e\n\u003cp\u003eGetting started is easy. Plug it in over USB-C, connect the included FPC antenna to the UFL connector, and follow Seeed's Getting Started guide. If your project runs on battery, there's a built-in battery interface for a 3.7V LiPo with charging support. Seeed quotes a deep-sleep current of around 15 µA when powered through the battery pads with low-power firmware. Security features include secure boot, flash encryption and hardware cryptographic accelerators.\u003c\/p\u003e\n\u003cp\u003eThe result is a small, low-cost board that can handle a modern smart home or IoT project, with clearer 5 GHz connections when you need them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e The pin headers come loose in the bag and need to be soldered on if you want to use a breadboard or plug the board into headers. Matter, HomeKit and MQTT support depends on the SDK and firmware you choose.\u003c\/p\u003e\n\u003ch4\u003eOverview\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli class=\"\"\u003eFirst Seeed Studio XIAO

Seeed says the Arduino IDE is supported through the nrf54-arduino-core. For battery projects, connect a 3.7V LiPo and let the nPM1300 manage charging. According to Seeed, deep-sleep current is as low as 4.76 µA and ship mode drops to 0.33 µA.

You run out of pins once you add a display and a few sensors.

Connect over USB-C and program it in the Arduino IDE, PlatformIO, MicroPython or CircuitPython. The SAMD21 has native USB, which makes it great for custom keyboards, macro pads, MIDI controllers and other USB HID projects. For portable builds, connect a Li-ion battery to the battery pads on the back. The board can run from USB, from the battery or from both at once, with backflow protection and a charge LED to show charging status.\u003c\/p\u003e\n\u003cp\u003eThe result is the XIAO you know, with more pins, built-in battery charging and fewer extra parts in your project.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e The 16 extra GPIO are on 1.27 mm pitch SMD castellations, so they're designed to be soldered to a carrier board or custom PCB, not plugged into a breadboard.

Once you add a display, some buttons and a few sensors, you run out of pins. Running it from a battery means adding a separate charger board, and you still can't easily tell how much charge is left.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSeeed Studio XIAO RP2040 Plus\u003c\/strong\u003e fixes this without making the board any bigger. It keeps the same \u003cstrong\u003eRaspberry Pi RP2040\u003c\/strong\u003e, with two ARM Cortex-M0+ cores at up to 133 MHz, plus 264 KB SRAM and 2 MB Flash. Redesigned castellations add \u003cstrong\u003e15 extra GPIO\u003c\/strong\u003e. It also adds an \u003cstrong\u003eonboard PMIC for Li-ion battery charging\u003c\/strong\u003e, \u003cstrong\u003ebattery voltage monitoring you can switch on in software\u003c\/strong\u003e, Reset and Boot buttons, and a programmable RGB LED.\u003c\/p\u003e\n\u003cp\u003eGetting started is easy. Connect over USB-C and program the board in the Arduino IDE, MicroPython or CircuitPython. You can also use the RP2040's PIO state machines for precise timing jobs such as driving LEDs or custom protocols. For portable builds, connect a Li-ion battery to the pads on the back. Your code can switch on battery sensing with GPIO24 and read the battery voltage on GPIO29 (A3), which is handy for low-battery warnings and data loggers.\u003c\/p\u003e\n\u003cp\u003eThe result is the RP2040 XIAO you know, with more pins, built-in battery charging and a simple way to check battery level.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e The 15 extra GPIO are on 1.27 mm pitch SMD castellations, so they're designed to be soldered to a carrier board or custom PCB, not plugged into a breadboard. The two included 7-pin headers come loose in the bag and give you the standard 2.54 mm XIAO pins once soldered. GPIO29 (A3) is shared with battery sensing, so it can't be used as a general pin while you're measuring the battery. No battery or USB cable is included.\u003c\/p\u003e\n\u003ch4\u003eOverview\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli class=\"\"\u003eRaspberry Pi RP2040, dual ARM Cortex-M0+ at up to 133
