We greatly value all our customers and therefore we want to improve our services for them. We have now introduced the option to pay in our E-Shop using PayPal, so you can pay either from your PayPal account, if you have one, or by credit or debit card. It is no longer necessary to pay by bank transfer. We previously tried to set up a payment gateway through a bank, but this is only available for larger sales volumes, so it was rejected.
We are also introducing the option of shipping via Packeta. You can have your shipment sent to your address or pick it up at thousands of pickup points and boxes, not only in the Czech Republic and Slovakia, but also in most European countries. We also ship to the USA, for example. We do not yet have an integrated function for searching for pickup points directly in our E-Shop, so you will need to click on the link, search for a pickup point, and enter it in the comments, but we believe you can handle it.
Thank you all for your support. If you have any questions, please do not hesitate to contact us.

I have already participated in the 1000-mile race across Czechia and Slovakia three times, and it has been five years since my last participation. The race is being held this year for the sixteenth time, and I have registered again. Since I use a mobile phone for navigation (I need it anyway), which is much more convenient and ultimately more reliable than dedicated navigation devices, I developed the DYNABANK power bank, which is charged from a bicycle dynamo hub. I feel that it needs to be innovated, so I am planning a new version for this race. Since I still have a lot of assembled PCBs, it is probably best time to sell them. Therefore, it will now be offered at a reduced price, where I am basically ignoring the entire assembled PCB. At a time when everyone is used to buying low-cost Chinese goods, let's take a look at history and the production cost.

The PI module family has grown with the addition of another processor module with an STM32F303 microcontroller, which is suitable for basic control or reading of analog or digital sensors. The processor runs at a frequency of 72 MHz, has 128 kB of FLASH memory, 32 kB of RAM, and 8 kB of faster CCMRAM memory, and also allows to run FreeRTOS. Of course, it also supports our peripheral submodules.

When testing developed products, EMI emissions are an important parameter. Testing in accredited laboratories is expensive, so pre-certification tests are performed to verify emissions. This requires an EMI receiver or spectrum analyzer, as well as a LISN (line impedance stabilization network).

The PI-RSX module allows you to add RS-232, RS-485, or RS-422 interfaces to your Raspberry Pi. Everything is contained in a single module, and the interface type is selected using jumpers on the PCB. Let's take a look at how to use it in Python.

The PI-CAN module is a module with a galvanically isolated CAN FD interface based on the MCP2518FD controller with the MCP2544FD interface. Support for PI-CPUF407 is included in the sample application on GitLab. Let's also take a look at how to get it running on Raspberry OS.

The DYNABANK power bank for cycling, rechargeable from a hub dynamo, is now also available in a 5,000 mAh version called DYNABANK 5, which is smaller in size and lighter in weight than the original DYNABANK 10 version with a 10,000 mAh capacity.

There are two new modules for Raspberry Pi or PI-CPUF407. One is the PI-CAN module with CAN FD interface with speeds up to 8 Mbit/s and the other is the PI-RSX combination module with optional RS-232, RS-485 or RS-422 interfaces. These are stackable HAT+ modules with integrated EEPROM for module detection and both with LED activity indication.

The PI-AIO and PI-DIO modules are connected to the Raspberry Pi on the I2C bus on pins GPIO2 (SDA) and GPIO3 (SCL). Therefore, the I2C stack, which is already integrated in the Raspberry OS, can be used for control. Let's take a look at how to do this in the Python programming language.

Three modules have been developed with digital and analogue interfaces not only for the PI-CPUF407. This includes the PI-FIO module, designed for direct use of the interfaces on the STM32F407 processor, as well as PI-DIO with galvanically isolated digital inputs and outputs and PI-AIO with galvanically isolated analog inputs and outputs. PI-DIO and PI-AIO are compatible with the HAT+ standard for Raspberry Pi.
