Pichanon Suwannathada and the Lambda Nu Co. Ltd. team have taken to Crowd Supply to launch an open source, Arm-powered board for real-life applications that aims to reduce the cost of hardware for the developers through a curated set of inputs and outputs: D-MARK.
The board is based on an STM32F070RB MCU running at 48MHz with built-in DMSI along with an auxiliary ATtiny84A pre-programmed to work as a transparent input/output. According to the Suwannathada, the board is equipped with a real-time clock function unlike the STEVAL-SPIN3201.
One of the main features is that it has the dual functionality of sensor and controller in a single board. With this, the D-MARK supports a large number of onboard communications through USB Type-B female and USB Type-A female, plus a microSD card slot.
D-MARK comes with an open source D-MARK Script Interpreter firmware (DMSI). Suwannathada notes that since there's no IDE, there is no need to program or compile the code. This enables you explore the capabilities of the board without firmware programming.
The crowdfunding campaign is now live over on Crowd Supply, with the D-Mark controller board priced at $89 (including a microSD card). There's also a stepper motor driver module available for an additional $10. The board is expected to start shipping by 18th July 2021.
