Modules for Embedded Projects – Microcontrollers and Peripherals, Designed In-House
This category contains modules developed and manufactured in-house. The range covers compact microcontroller modules based on established ARM and AVR architectures, as well as specialised peripheral modules – designed for professional use in embedded applications, from prototyping through to small and medium production runs.
In-House Development & Manufacturing
The modules in this category are proprietary designs – developed from concrete application requirements and manufactured in-house. A number of companies already use these modules in their own products. Enquiries for larger quantities or project-specific requirements are welcome.
Perfboard & Carrier Boards
Many modules route their connections to 2.54 mm pitch connectors, making them suitable for direct assembly on perfboard systems or for use with a custom carrier board – either soldered permanently or plugged in with receptacles.
Quality Manufacturing
FR4 PCBs with immersion gold finish (NiAu), solder resist, RoHS compliant. Decoupling provisions on all relevant supply rails; interfaces fitted with EMC components.
ARM Cortex-M0+ & AVR
Microcontroller modules based on Atmel/Microchip SAM D (ARM Cortex-M0+) and ATmega (AVR) – established architectures with broad tool support (Atmel Studio, CMSIS, Arduino framework). ARM modules include a Cortex Debug connector (SWD, 10-pin, pin-compatible with Atmel-ICE); AVR modules include an ISP header.
Peripheral Modules
Alongside microcontroller modules, the category also includes peripheral modules. Currently: the TuneSOne audio module (MP3 MPEG1/2 Layer III, Class-D amplifier 1 W/8 Ω, SPI interface with level shifting, 32 MB flash, Windows software for audio container creation). Further modules will be added.
The range in this category grows with new in-house developments. Companies wishing to use our modules in their own products are welcome to enquire about larger quantities.
MEGA2560-USB ist ein Mikrocontrollermodul mit ATmega2560 AVR-Mikrocontroller (Atmel) und CP2102 USB-UART-Bridge (Silabs). Das Mikrocontrollermodul ist durch seine sehr kleine Bauform (30mm x 63mm) und den komplett an den zwei 50-poligen 2-reihigen Pad-Reihen verfügbaren Mikrocontroller-Pins, die auf dem Rastermaß 2,54mm liegen, sehr gut in Verbindung mit Lochraster-Systemen einsetzbar. Wahlweise kann das Modul mit Stiftleisten mit der Mutterplatine verlötet oder kombiniert mit Federleisten gesteckt werden.Die Spannungsversorgung des Mikrocontrollermoduls erfolgt wahlweise durch die USB-Betriebsspannung VBUS 5,0V eine externe Spannungsquelle 4,5V bis 5,5V eine externe Spannungsquelle 6,1V bis 9,0V (LowDrop-Linearregler 5,0V befindet sich auf dem Modul) Das Mikrocontrollermodul wird mit bestückter 6-poligen ISP Stiftleiste ausgeliefert. Ein RTC-Quarz (32.768Hz an TOSC1/2, SMD) ist bestückt. Bestellen Sie bitte einen Systemtakt-Quarz oder/und eine Quarz-Fassung separat, beides finden Sie in unserem Onlineshop. Sie möchten, dass wir den Quarz oder die Quarz-Fassung für Sie bestücken? Teilen Sie uns dies bitte einfach im Bemerkungsfeld bei Ihrer Bestellung mit.Eigenschaften: Microcontrollermodule with ATmega2560-AU AVR microcontroller and Silabs CP2102 USB-UART bridge.

With the TuneSOne audio module, you can easily add audio and voice output to your project. Main Features The audio decoder module supports MP3 MPEG 1 and 2 Audio Layer III formats with constant and variable bit rates up to a data rate of 320 kBit/s. The integrated Class D audio amplifier can drive an 8-ohm speaker with an output power of 1 W. It features a circuit for reducing clicks and pops, as well as active emission limiting, slew rate limiting, and overshoot control to significantly reduce EMI. The module has an SPI interface with a user-friendly protocol and a level translation function (VDDIO 3.3 V to 5 V). The audio files are stored in a flash memory with 32 MB storage capacity and are located in a robust file container. The audio file container is programmed into the flash memory via a microSD card. The audio file container is created using the TuneSOne Windows software. The source audio files for the project are stored in a project directory and managed via Windows Explorer. This makes it easy to port, modify, expand, and duplicate the project.
