Hi Henri10, We have a similar combination of a Cortex-M0 (SAMD20 from Atmel (now Microchip)) and the BMX055 in a single package known as the BMF055. It is a recommended alternate to get started with BSX Lite integration on a Cortex M0. Product page of the BMF055 : https://www.bosch-sensortec.com/bst/products/all_products/bmf055 BSX Lite integration guide : https://ae-bst.resource.bosch.com/media/_tech/media/application_notes/BST-BMF055-EX003-00.pdf Additionally, the BMF055 comes preprogrammed with a stock bootloader that supports UART, SPI and I2C host interfaces for loading your application during production. All links and references can be found under downloads. Regards, kgoveas
