  • 512MB RAM
  • Mini-HDMI port
  • Micro-USB OTG port
  • Micro-USB power
  • HAT-compatible 40-pin header
  • Composite video and reset headers
  • CSI camera connector (v1.3 only)

Description

We apologise that, due to high demand, we are temporarily not able to take back orders for the Raspberry Pi Zero.

Introducing the latest addition to the Raspberry Pi Family – the miniature Raspberry Pi Zero!

The Raspberry Pi Zero is the latest single board computer to be released by the Raspberry Pi Foundation. It is the entry level model Raspberry Pi perfect for hobbyists, makers and industrial engineers looking to create solutions where small size and low power consumption are important. This is especially relevant for applications in the wearables space as well as up and coming applications like IoT (internet of things) devices, embedded hardware that does not require the quad-core power of the Raspberry Pi 2B and a multitude of other applications.

Key Features

  • The Pi Zero utilises the single-core BCM2835 processor, which can now be over-clocked to 1GHz
  • 512MB onboard RAM
  • Micro SD port for storage and operating system
  • Micro USB Power Input
  • Micro USB data port for linking to accessories and peripherals like an external USB hub, or for connecting to your PC (Micro USB “On the Go” adapter is supplied to connect your standard USB devices)
  • The 40 pin GPIO is unpopulated providing the flexibility to use only the connections your solution requires
  • The Pi Zero supports full HD 1080P output via Mini HDMI or using RCA composite video output via the unpopulated pins (Mini HDMI to HDMI adapter is supplied to connect to your display)
  • Power rating of just 160mA even when connected to a 1080P display, making this the most efficient Raspberry Pi to date

Technical Specifications

  • Power: 5V, supplied via micro USB connector, drawing 160mA (even when connected to an HD display).
  • RAM: 512MB
  • CPU: Broadcom BCM2835 ARMv6 system-on-a-chip, running at up to 1GHz
  • Dimensions: 65mm x 30mm x 5mm
  • Storage: MicroSD card
  • Video and Audio: 1080P HD video output. Audio output via mini-HDMI connector
  • Operating System: Linux / Raspbian / NOOBS and many others

Inputs and Outputs

  • MicroSD Card Slot: The Pi Zero gets its storage space from a MicroSD card, which you’ll need to install the operating system on.
  • Mini HDMI: Video output for the Pi Zero is by way of a mini-HDMI connector. In terms of their operation, these connectors perform identically to their larger versions. Just be aware that you’ll need a mini-HDMI to standard HDMI cable for your monitor or TV.
  • Micro USB: You’ll notice there are two micro USB connectors on the Pi Zero. One is for data (the connector on the left, if the MicroSD card slot is on the left), and one is for power. Don’t get them mixed up. For the data one, you might want to get a cable or an adapter so you can connect a USB hub, and therefore all your peripherals (keyboard, mouse etc).
  • GPIO: The Pi Zero has the same 40 pin General Purpose Input/Output connections as the Model A+, B+ and RPi2, but the connector pins are unpopulated. So if you want to use the GPIO, you’ll either have to solder the required pins in place, or solder your connections directly to the Pi Zero.
  • RUN Mode Pins: There are two unpopulated RUN mode pins, which can be used to connect a reset button to the Pi Zero. Again, you’ll either have to add the pins yourself, or solder the button straight to the board.
  • Composite Video: Here’s an interesting one. There’s an RCA composited video output via two (unpopulated) pins, so you can hook the Pi Zero up to older display equipment that accepts a phono plug as an input

8-level Bi-directional Logic Level conversion module 5v - 3V Level Converter 8 channel for Raspberry pi
close

This module uses an array of transistors with pullup resistors to provide an 8 channel bi-directional voltage level conversion (level shifting) for digital logic signals. Intended mainly for the conversion of signals between 3.3V and 5V logic levels this module provides a way of safely interfacing a 5V microcontroller to a 3.3V device or conversely 3.3V microcontroller to a 5V device without risking damage to both devices. Each of the 8 channels can also work in both directions meaning that bi-direction 2 way data signals can also be level shifted. Each side of the array can be supplied separately with the required level shifting voltage which can range anywhere between 1.8 and 6V. 

Specification:

Product code: HCMODU0113
8 channel 2 way bidirectional conversion
Voltage conversion range: 1.8V to 6V
Module dimension (excluding header pins): 27.5 x 28mm
