Raspberry Pi Compute Module 4 vs Compute Module 3

Raspberry Pi launched Compute Module 4, as a successor to Compute Module 3B+. The Compute Module 4 (CM4) is a so-called System on Module (SoM), which contains core parts which make up a Raspberry Pi 4, for example, and in addition to that eMMC Flash in different sizes (ranging from none for the Lite module [...]

Lite version of PCCB

The PCCB is a carrier board for the Raspberry Pi Compute Module 1 – 3 B+.We are able to remove any parts of the full PCCB you do not need, thereby cutting your BOM cost & time to market significantly:For this particular customers only the following features remained:10 / 100 Mbit/s LAN port (Ethernet)DC step-down [...]

Controlling LEDs on Alpine Linux using the command line

We have developed an embedded Raspberry Pi Compute Module carrier board for industrial use: the PCCB.As you can see, there are three (directly) user programmable LEDs on the PCCB: USER / INFO / ACT.These are defined in the device tree. For example, we can define the following in our device tree overlay://LEDs fragment@11 {   target [...]

Will the Raspberry Pi 400 be available in an 8GB version?

The Pi400 already has a lot of basic models due to the languages, which of course is a bigger logistic challenge for Raspberry Pi and its partners.The standard version of the Pi 400 with 4 GB covers most (consumer / school children / students) application purposes. 8 GB are rather needed in the area of [...]

The technology & security foundations of PiCockpit

I was asked to elaborate a bit about the security & technology foundations of PiCockpit.The parts which are involvedPiCockpit consists of several parts:picockpit-clientpicockpit-frontendpicockpit-backendpicockpit-api (“papi”)the databasethe MQTT serverthe picockpit Package repositoryThe MQTT serverData between the picockpit-frontend and picockpit-client is exchanged using the MQTT server (called “broker”), via Websockets. We use VerneMQ for this purpose. MQTT is [...]

Update picockpit-client for compatibility with v2.0

The new PiCockpit release has many new features, which require a new picockpit-client version (at least v2.0.1) for compatibility. What do you get by upgrading the picockpit-client / using PiCockpit v2.0?GPIO: control GPIO pins (input / output / software PWM to dim LEDs for example)PiControl: run commands on your Pi from the webinterface (you define [...]

Stress testing a Raspberry Pi 4 with PiCockpit – temperature monitoring

Using the new PiCockpit v2.0 release, you can monitor the current SoC temperature of the Pi in an easy to use webinterface (in PiStats).Simply click on PiStats, and enter temp into the search:this will narrow the display down to just the SoC temperature. The temperature will be updated every second.I also recommend you to use [...]

How to bring up the camera and display on a compute module carrier board

We have developed our own Compute Module Carrier Board, called PCCB. It is compatible with Raspberry Pi Compute Modules 1 – 3 Plus, and has a number of very useful features for industrial use (RS232, CAN Bus, RS485, TPM, DC/DC Stepdown).Today, I verified the camera and 7’’ display interface which we provide on the board [...]
