For a detailed description, refer to its user manual on the product web page. Additional information is available from the datasheet and reference manual of the target STM32. Table 1. Ordering information Order code Board reference User manual Target STM32 B-L4S5I-IOT01A MB1297 UM2708 STM32L4S5VIT6U 1.1 Product marking Evaluation tools marked as ES or E are not yet qualified and therefore not ready to be used as reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference designs or in production. E or ES marking examples of location: On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the STM32 datasheet Package information paragraph at the www.st.com website). Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board. This board features a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a marking option at the end of the standard part number and is not available for sales. In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties. 1.2 Codification The meaning of the codification is explained in Table 2. Table 2.
