 clock speed to 1.2 GHz (1200 MHz), or by 30%, as well as the VideoCore IV 500 MHz graphics core, resulting in improved graphics performance. Of course, appropriate cooling of the chip is required, which can be accomplished by bonding an aluminum finned heatsink.
The Broadcom VideoCore IV graphics processor supports OpenGL ES 1.1, 2.0, as well as H.264 and MPEG-4 video decoding (1080p30). The highest resolution is full HD, which is 1920 x 1080 pixels, or 1080p. To connect the monitor, a tiny HDMI connector is available. To connect the RPi Zero to the monitor, you’ll need a mini HDMI-to-HDMI converter or a cable with a mini full-size HDMI connector on one end and a regular full-size HDMI connector on the other. Alternatively, you can use a composite video connection, with the signal available at the test point via the RCA (Cinch) connector.
You can use this way, for example, to connect to older TVs that lack an HDMI input. You’re probably wondering why the Raspberry Pi is linked to an old TV. One of the reasons is that there are various preconfigured vintage video game operating system variations, such as Retro Pie, available for the Raspberry Pi Zero. Retro games, on the other hand, have the proper atmosphere on a retro TV. For miniature projects, the display on a suitable LCD display connected via the SPI interface can be used.
On the PCB, there are two micro USB ports. One is powered, while the other utilizes the USB 2.0 standard for connecting external devices like keyboards and mice. To connect devices with a USB-A connector, a USB OTG (On-The-Go) reduction must be used. For example, you can use a kit that employs a common USB radio dongle, an active USB hub, or a keyboard with an integrated touchpad to overcome the difficulty of attaching a keyboard and mouse to a single port.
Because the GPIO connectors and the CSI connector for connecting the camera are the same as on other Raspberry boards, projects made for prior boards can be readily moved to a newer, more powerful board. Bluetooth 4.2, including Bluetooth Low Energy, is supported by the Raspberry Pi Zero 2W. (BLE). When connecting to WiFi, keep in mind that the printed circuit board contains a small antenna, thus the connection works best if the board is close to the WiFi router.
To familiarize yourself with the development board’s capabilities, we recommend modules from Grove kits built for quick prototyping.
Sensors, motors, servo motors, relays, displays, LEDs, rotary encoders, and other hardware components are included in the kits. Each module in the kit is meant to perform a single function, such as monitoring temperature, humidity, measuring distance using ultrasound, presenting data on the screen, and so on. Simply plug in the Base Shield motherboard and you’re ready to put your ideas to the test. The Grove Base hat expansion board for the Raspberry Pi Zero is required for the Raspberry Pi Zero development board. The connectors are designed to be inserted correctly only.
All that is required is that you connect the analog interface modules to the analog connectors, the modules that require digital inputs to the digital connectors, and the outputs to the digital connectors. which use the communication bus must be connected to the relevant communication interface socket I2C, UART, and servomotors to the PWM connections. Even if you make an unintentional error, you will not cause any harm; however, the connection will not work for you. Because the Raspberry lacks analog inputs, another STM32 microcontroller on the Grove Base hat supplies a 6-channel 12-bit ADC converter.
Screens, various single-purpose measuring or communication devices, multimedia centers, mini-game consoles with color displays, monitoring cameras, audio converters, measuring devices, or robotic constructions are among the many extension modules available.
