The ESP8266 is an impressive, low cost WiFi module suitable for adding WiFi functionality to an existing microcontroller project via a UART serial connection. The module can even be reprogrammed to act as a standalone WiFi connected device – just add power! 802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-AP Integrated TCP/IP protocol stack This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino , for example, because the ESP-01 acts as a small computer. Thus, you can give a microcontroller internet access like the Wi-Fi shield does to the Arduino, or you can simply program the ESP8266 to not only have access to a Wi-Fi network, but to act as a microcontroller as well, which makes the ESP8266 very versatile.

This anodised aluminium heatsink case will protect your Raspberry Pi 4 and give you very effective passive cooling. It's great in cases where you want completely silent cooling, for instance, if you're building a home media center. The scope of delivery includes a thermal pad to provide thermal contact between the CPU and top case, and a handy Allen key and set of hex bolts to attach the case together. The case gives you access to all of the ports, pins, and connectors. Features Anodised aluminium top and bottom case Heatsink fins Thermal pad Hex bolts and Allen key included Access to all ports, pins, and connectors Compatible with Raspberry Pi 4 Assembly Assembling your heatsink case is pretty easy and should only take a couple of minutes. The first, and most important thing is to make sure that your Pi is powered off and unplugged before you fit the case. Take one of the thermal pads and peel the protective films off both sides of it (there's a white film and an easy-to-miss clear film on the other side. Stick the thermal pad onto your Pi's CPU (the metal square nearest the middle of the PCB). Sticking the thermal pad to the CPU first is a much better way to position it correctly than trying to stick it to the case. Only use one thermal pad with the Raspberry Pi 4. Position the top case and then, holding it in place, flip the whole thing over and position the bottom case on the underside of your Pi. Use the four hex bolts and allen key to secure the case. Notes The case is metal and hence conductive, so be careful not to short any components on it, and ensure that your RPi is powered off and unplugged when fitting the case It may be obvious, but the case will get hot in use Dimensions: 87 × 56 × 25.5 mm

The Arduino Giga R1 WiFi brings the power of the STM32H7 to the same form factor as the popular Mega and Due, being the first Mega board to include onboard Wi-Fi and Bluetooth connectivity. The board provides 76 digital inputs/outputs (12 with PWM capability), 14 analog inputs and 2 analog outputs (DAC) all easily accessible via pin headers. The STM32 microprocessor with dual-core Cortex-M7 and Cortex-M4, together with onboard memory and audio jack enables you to perform machine learning and signal processing on the edge. Microcontroller (STM32H747XI) This dual core 32-bits microcontroller allows you have two brain talking to each other (a Cortex-M7 at 480 MHz and a Cortex-M4 at 240 MHz) you can even run micropython in one and Arduino in the other. Wireless communication (Murata 1DX) Whether you prefer Wi-Fi or Bluetooth, the Giga R1 WiFi got you covered. You can even quickly connect to the Arduino IoT Cloud and keep track of your project remotely. And if you are concerned about the security of the communication, the ATECC608A keeps everything under control. Hardware ports and communication Following the legacy of the Arduino Mega and the Arduino Due, the Giga R1 WiFi has 4x UARTs (hardware serial ports), 3x I²C ports (1 more than its predecessors), 2x SPI ports (1 more than its predecessors), 1x FDCAN. GPIOs and extra pins By keeping the same form factor of the Mega and the Due, you can easily adapt your custom made shields to the Giga R1 WiFi (remember this board works at 3.3 V though!). Also, additional headers have been added so that the total number of GPIO pins is now 76, and two new pins have been added: a VRTC so you can connect a battery to keep the RTC running while the board is off and an OFF pin so you can shut down the board. Connectors The Giga R1 WiFi has extra connectors on board which will facilitate the creation of your project without any extra hardware. This board has: USB-A connector suitable for hosting USB sticks, other mass storage devices and HID devices such as keyboard or mouse. 3.5 mm input-output jack connected to DAC0, DAC1 and A7. USB-C to power and program the board, as well as simulate an HID device such as mouse or keyboard. Jtag connector, 2x5 1.27 mm. 20-pin Arducam camera connector. Higher voltage support: In comparison with its predecessors that support up to 12 V, the Giga R1 WiFi can handle a range of 6 to 24 V.
