The ESP32-C6 SuperMini is the SuperMini that carries every radio. WiFi 6, Bluetooth 5.3 LE and an 802.15.4 radio for Zigbee 3.0, Thread and Matter all sit on one 26 x 18mm USB-C board, which is what lets a C6 be the border router or coordinator for a mesh rather than just another node on it. It breaks out 22 GPIO across two castellated rails and five inner holes, and there are B+ and B- pads on the underside feeding an onboard lithium charger, so a battery powered sensor needs nothing but a cell.

2.54mm male header strips

Supplied loose, not fitted, and longer than the rails need, so snap them to ten positions per side. Solder them straight, right-angle or low-profile to suit your build, or leave them off and reflow the board by its castellated edges.

Good to know: Logic is 3.3V and the GPIO are not 5V tolerant. Program it through the free Arduino IDE with the Espressif esp32 board package version 3.0 or later (earlier cores have no C6 support), select ESP32C6 Dev Module and set USB CDC On Boot to Enabled, or use PlatformIO, ESP-IDF or ESPHome. Plug in with a USB-C data cable; if no port appears, hold BOOT, tap RESET, release RESET, then release BOOT. Do not power the 5V pad while USB-C is plugged in, and use only one source at a time. Three marks on the top face annotate LEDs rather than pads: 15 beside the blue LED, 8 beside the RGB LED and BAT beside the charge LED. The underside silkscreens the GPIO number of every pad, which is the quickest way to read this board. The two inner holes marked 12 and 13 are the native USB data lines, so using them as ordinary GPIO costs you the USB console.

Frequently Asked Questions

Answers to the questions buyers ask most.

What does the C6 add over the C3 SuperMini?

Two things. The WiFi radio moves from WiFi 4 to WiFi 6, which mostly buys you better behaviour on a busy network and lower power through target wake time rather than raw speed. More importantly the C6 adds an 802.15.4 radio, so it can join or run Zigbee 3.0, Thread and Matter networks, which the C3 cannot do at all. The C6 also brings out 22 GPIO against the C3's 13, and adds a low-power second core.

Can it be a Thread border router or a Zigbee coordinator?

Yes, and that is the main reason to pick a C6 over an H2. Because it has WiFi and 802.15.4 running at the same time it can bridge a Thread mesh onto your normal network. Espressif publish an ESP Thread border router example for the C6, and it is also supported as a Zigbee coordinator in the esp-zigbee-sdk. The ESP32-H2 has no WiFi, so it can only ever be a node behind something like this.

Do I need a WiFi 6 router?

No. The radio is backward compatible with 802.11b, g and n, so it joins any 2.4GHz network. You only get the WiFi 6 efficiency features, OFDMA and target wake time, when it is talking to a WiFi 6 access point. Note there is no 5GHz radio on this chip.

Can it run from a battery?

Yes. Two round solder pads marked B+ and B- sit on the underside beneath the USB-C connector, feeding an onboard single-cell lithium charger. Solder a 3.7V Li-ion or LiPo cell to them and it charges whenever USB-C is connected, with an LED showing charge state. The manufacturer does not publish the charge current, so assume a few hundred milliamps, use a protected cell and do not leave a charging board unattended.

How many pins does it actually have?

Twenty castellated pads, ten per rail, plus five inner through-holes and the two battery pads underneath. Between them they carry 22 GPIO. Watch out when reading the top face: the marks reading 15, 8 and BAT sit beside LEDs rather than pads. The underside is the easy way to read this board because it silkscreens the GPIO number of every pad: 5V, GND, 3V3, 20, 19, 18, 15, 14, 9, 8 down one rail and 16 (TX), 17 (RX), 0, 1, 2, 3, 4, 5, 6, 7 down the other, with 21, 22, 23, 12 and 13 on the inner holes.

What are the inner holes marked 12 and 13?

GPIO12 and GPIO13, which are the native USB data lines, D- and D+. They are broken out so you can get at them, but reconfiguring them as ordinary GPIO costs you the USB serial console and the ability to reflash without the BOOT button sequence. GPIO21, GPIO22 and GPIO23 on the other inner holes have no such commitment and are the cleanest spare pins on the board.

Which pins should I keep clear at boot?

GPIO8, GPIO9 and GPIO15 are strapping pins, and all three are used on this board: GPIO8 drives the WS2812 RGB LED, GPIO9 is the BOOT button, and GPIO15 drives the blue LED. Nothing you attach to those pads may hold them at the wrong level through reset, or the board will come up in download mode or with the wrong JTAG source instead of running your firmware.

Are the header pins fitted?

No. Two 2.54mm male header strips come loose in the bag and are longer than the board needs, so snap them to ten positions per rail. You can also skip them and reflow the board onto a carrier by its castellated edges, or solder wires straight to the pads.

Does it need a driver?

No. The chip drives USB itself and enumerates as a native USB Serial/JTAG device, so Windows, macOS and Linux all see it with the driver already in the operating system. There is no CH340 or CP2102 on this board. Use a USB-C data cable, not a charge-only one.

Which board do I select in the Arduino IDE?

Install the Espressif esp32 board package version 3.0 or later, then choose ESP32C6 Dev Module and set USB CDC On Boot to Enabled. On an older 2.x core the C6 does not appear in the Tools menu at all, which is the most common reason people think the board is faulty. For ESPHome use the esp32 platform with variant esp32c6 on the ESP-IDF framework.

How do I put it into download mode?

Hold BOOT, tap RESET, release RESET, then release BOOT. On the C6 the boot pin is GPIO9, not GPIO0 as on the C3 and S3, so wiring diagrams carried over from those boards will pull the wrong pin.

Can I power it from something other than USB?

Yes, but pick one source at a time. You can feed the 5V pad, or solder a cell to B+ / B-, or drive the 3V3 pad from a regulated 3.3V supply. TZT states the 5V pad accepts 3.3 to 6V; we suggest staying inside 4.5 to 5.5V because the onboard regulator is unspecified. Do not power the 5V pad while USB-C is also plugged in.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
