{"title":"Arduino MKR1000 WIFI","handle":"arduino-mkr1000-wifi","url":"/products/arduino-mkr1000-wifi","description":"The Arduino MKR1000 combines a powerful 32-bit ARM Cortex-M0+ microcontroller with built-in 2.4GHz Wi-Fi and hardware cryptographic authentication — all in a compact, IoT-ready form factor. It runs at 3.3V and includes an integrated Li-Po battery charging circuit, making it ideal for battery-powered wireless projects.\n\n\nWarning: The MKR1000 operates at 3.3V. Maximum I/O voltage is 3.3V — applying higher voltages will damage the board. Level shifting is required for bidirectional communication with 5V devices.\n\n\nKey Features\n\n\nMicrocontroller – ATSAMW25 SoC: SAMD21 Cortex-M0+ 32-bit ARM MCU\n\nWi-Fi – WINC1500 2.4GHz 802.11 b/g/n (single 1×1 PCB antenna)\n\nCryptographic Security – ECC508 CryptoAuthentication chip; SHA-256 certificate support\n\nLi-Po Battery Charging – Integrated charging circuit; auto-switches between USB/VIN and battery\n\nUSB – Full-speed USB device and embedded host; powers board at 5V\n\n\nSpecifications\n\n\nOperating Voltage – 3.3V\n\nInput Voltage – 5V (USB or VIN, max 6V)\n\nFlash Memory – 256KB\n\nSRAM – 32KB\n\nClock Speed – 48MHz (CPU), 32.768kHz (RTC)\n\nDigital I/O Pins – 8\n\nPWM Pins – 12\n\nAnalog Input Pins – 7 (8/10/12-bit ADC)\n\nAnalog Output Pins – 1 (10-bit DAC)\n\nInterfaces – 1× UART, 1× SPI, 1× I2C\n\nDC Current per I/O Pin – 7mA\n\nDimensions – 61.5 × 25mm\n\nWeight – 32g\n\n\nBattery Requirements\n\n\nType – Li-Po single cell, 3.7V, minimum 700mAh\n\nConnector – 2-pin JST PH type (female on battery, male on board); Left pin = positive, Right = GND\n\nCharging Current – 350mA preset; minimum 700mAh battery required to avoid damage\n\nCharge Limit – 4 hours / max ~1400mAh per charging cycle, then auto sleep\n\n\n\nNote: The onboard LED is connected to D6 (not D13 as on other Arduino boards). Update Blink sketches accordingly. The CHARGE LED may blink at ~2Hz if no battery is connected, the battery is overdischarged, or a full battery is reconnected — this is normal behaviour.\n\n\nIdeal For\n\nBattery-powered IoT devices and wireless sensor nodes\nSecure Wi-Fi connected Arduino projects\nCompact, low-power embedded applications\n\n\nResources\n\nArduino Getting Started Guide\nWiFi101 Library Reference\nSchematic (PDF)\nEagle Files (ZIP)\nFritzing Files (ZIP)\nJST PH Connector Datasheet\n","vendor":"Pimoroni","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":7680,"title":"Default Title","sku":"PI-ABX00011","price":92.46,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
