Raspberry Pi 3.2″ Touch Screen and Modules Kit Review

I show you what’s inside the Waveshare 3.2″ Touch Screen and Modules kit for the Raspberry Pi and talk about the main parts of the boards and their functions. There’s a lot of cool stuff in here that I can’t wait to start experimenting with.

Raspberry Pi Compute Module 3 (CM3) aims to consumer products

Sort of announced in July 2016, the most recent Raspberry Pi Compute Module 3 (CM3) is considered to arrive at the market soon. Last Oct computer system equipment maker NEC already announced a new range of professional P and V Series large format displays that easily embed the RPi CM3 module. The new module, offered in two models – CM3 and CM3L (lite) – will complement the CM1 module launched before.

Specifications for the CM1, CM3 and CM3L SODIMM modules can be found in the data sheet accessible on the RPi internet site
. Where the CM1 was based on a BCM2835 processor chip (as employed on the original RPi and RPi B+ models), the CM3 features a quad-core 1.2 GHz BCM2837 chip, like the RPi 3. It consists of 1 Gigabytes of LPDDR2 RAM and 4 Gigabytes eMMC Flash. The ‘L’ version is a CM3 with no eMMC Flash, enabling the client to install his/her individual SD/eMMC unit. The pinout of the CM1 and CM3 modules are exactly the same but the CM3 module is one millimeter higher (31 mm).


The price of the new modules is not known yet, but since a CM1 retails at roughly £20, a very similar price may well be predicted for the CM3.

The CM3 is founded upon the Raspberry Pi 3 hardware and is for the purpose of industrial use in order to supply a cheap way for individuals to make tailored products based upon the Pi hardware and software system. The Compute Module products is more compact and has less abilities and ports than a regular Raspberry Pi, which makes it well suited for Internet of Things (IoT) products.

“The module utilizes a standard DDR2 SODIMM form factor, sockets for which are made by several producers, are simply accessible, and additionally are low priced,” Raspberry Pi COO and hardware lead James Adams mentioned in a post.

There are 2 variants of the CM3. The following are the specifications for both of them:

Standard Version:

BCM2837 central processor at to a maximum of 1.2GHz
4GB of on-module eMMC flash

Lite Version:

BCM2837 processor at to a maximum of 1.2GHz
Sdcard interface on Module pins consequently an individual can connect it up to an eMMC or Sdcard of their choice

Both versions can be slotted into a newly released Compute Module IO Board V3 (CMIO3) which helps you to do the following:

Delivers required power to the CM3
Permits you to program the CM3 Standard’s flash memory or to utilize an Sdcard on the Lite version.
Access the processor interfaces in a a tad bit more friendly fashion (pin headers and flexi connectors, just like the Pi)
Offers the needed HDMI and USB connectors in order that you have an entire system that can boot Raspbian (or maybe the OS of your preference).

“This board gives you both a starting template for those who want to design with the Compute Module, and a quick way to begin with experimenting with the hardware, and building and testing a system, before you go to the money necessary for fabricating a custom made board,” Adam said.

The older Compute Module model will still be offered, for folks who wouldn’t like the CM3’s performance betterment. As reported by the Raspberry Pi official mag The MagPi:

“With some caveats, the CM3 can be used a drop-in replacement for the CM1 being that they are pin compatible; the CM3 is 1mm taller, nevertheless, while the CPU can pull considerably more current from the VBAT power source line and will deliver a great deal more heat under heavy load.”
