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 [...]
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 [...]
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 [...]
LetsTrust TPM ist eine Aufsteck-Platine mit elektronischen Komponenten in den Abmessungen 12 mm x 15 mm x 5 mm. Sie ist zum Einsatz mit dem Raspberry Pi Einplatinencomputer vorgesehen. Die Hauptkomponente von LetsTrust TPM ist ein Kryptographie-Chip, der Infineon Optiga™ SLB 9670 TPM 2.0. Die anderen Komponenten auf LetsTrust TPM sind passive Komponenten, sowie eine [...]
The PCCB is our Raspberry Pi Compute Module carrier board with industrial interfaces:I will describe how to flash the PCCB flash using a Windows Computer. PrerequisitesUSB power supply (or DC power supply) PCCBcompute module with on-board flash (Raspberry Pi Compute Module Lite variants do not have Flash on board)microUSB to USB cable (note: some microUSB [...]
We are in the process of migrating to Gmail, to be able to delegate managing a mail server.We used ssmtp on our server to email mails before, using our own mail server (Zimbra).I have now managed to get Gmail Workspace working, and would like to share some pointers on how to do that. This is [...]
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 [...]
