COMING SOON – Adafruit QT Py ESP32-C3 WiFi Dev Board with STEMMA QT
Coming quickly! Signal as much as be notified when these are in inventory
What’s life and not using a little RISC? This miniature dev board is ideal for small tasks: it comes with our favourite connector – the STEMMA QT, a chainable I2C port, WiFi, Bluetooth LE, and loads of FLASH and RAM reminiscence for a lot of IoT tasks. What a cutie pie! Or is it… a QT Py? This diminutive dev board comes with a RISC-V IoT microcontroller, the ESP32-C3!
ESP32-C3 is a low-cost microcontroller from Espressif that helps 2.4 GHz Wi-Fi and Bluetooth® Low Power (Bluetooth LE). It has built-in USB-to-Serial, however not native USB – it can’t act as a keyboard or disk drive. The chip used right here has 4MB of Flash reminiscence, 400 KB of SRAM and might simply deal with TLS connections.
The ESP32-C3 integrates a wealthy set of peripherals, starting from UART, I2C, I2S, distant management peripheral, LED PWM controller, basic DMA controller, TWAI controller, USB Serial/JTAG controller, temperature sensor, and ADC. It additionally contains SPI, Twin SPI, and Quad SPI interfaces. There is no such thing as a DAC or native capacitive contact.
There’s a minimal variety of pins on this chip, it’s particularly designed to be low price and for less complicated tasks than ESP32-Sx or ESP32 classics with their massive variety of GPIO. Consider it extra as an meant substitute to the ESP8266 than to the ESP32!
With its state-of-the-art energy and RF efficiency, this SoC is a perfect selection for all kinds of utility situations regarding the Web of Issues (IoT), wearable electronics, and good properties.
Please notice: The C3 makes use of RISC V as a core, not Tensilica, and has Bluetooth LE (not traditional!). The BLE core helps BT model 5 together with Mesh
OLEDs! Inertial Measurement Models! Sensors a-plenty. All plug-and-play due to the modern chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so that you don’t even must solder! Simply plug in a appropriate cable and fix it to your MCU of selection, and also you’re able to load up some software program and measure some mild. Seeed Grove I2C boards will even work with this adapter cable.
Pinout and form are Seeed Xiao appropriate, with castellated pads. Along with the QT connector, we additionally added an RGB NeoPixel, a reset button (nice for restarting your program or getting into the ROM bootloader), and a button on GPIO 9 for getting into the ROM bootloader or for consumer enter
Runs Arduino with Espressif’s ESP32 core and you may as well run MicroPython on this chipset.
- Similar measurement, form-factor, and pin-out as Seeed Xiao
- USB Sort C connector – When you’ve got solely Micro B cables, this adapter will turn out to be useful!
- ESP32-C3 32-bit RISC-V single core processor with 4MB of Flash reminiscence, 400 KB of SRAM
- In-built USB-to-Serial contained in the chip, which will also be used for JTAG programming. This peripheral is just not native serial, so not for USB HID, MIDI, or MSC: it does cut back price since a separate converter isn’t wanted
- Can be utilized with Arduino IDE or MicroPython
- Constructed-in RGB NeoPixel LED notice that because of the small variety of GPIO, we couldn’t add a NeoPixel energy pin
- Battery enter pads on underside with diode safety for exterior battery packs as much as 6V enter
- 13 GPIO pins:
- 11 on breakout pads
- 5 x 12-bit analog inputs on A0 through A3 and SDA pin
- PWM outputs on any pin
- I2C port, on the breakout pads shared with the STEMMA QT plug-n-play connector
- {Hardware} UART which can be the {hardware} serial debug port
- {Hardware} SPI
- {Hardware} I2S on any pins
- 3.3V regulator with 600mA peak output
- Mild sleep at 500uA, deep sleep at ~300uA. Decrease energy deep-sleep is just not attainable as a result of we don’t have an additional GPIO for disabling the NeoPixel energy and we didn’t need to share that with any of the IO pads. An engineering trade-off!
- Reset swap for beginning your venture code over, boot 9 button for getting into bootloader mode
- Actually actually small
