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 microcontroller. Table 1. List of available products Order code Board reference User manual Target STM32 STM32L0538-DISCO MB1143 UM1775 STM32L053C8T6 1.1 Product marking The stickers located on the top or bottom side of the PCB provide product information: Product order code and product identification for the first sticker Board reference with revision, and serial number for the second sticker On the first sticker, the first line provides the product order code, and the second line the product identification. On the second sticker, the first line has the following format: MBxxxx-Variant-yzz, where MBxxxx is the board reference, Variant (optional) identifies the mounting variant when several exist, is the PCB revision andz is the assembly revision, for example B01. The second line shows the board serial number used for traceability. 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. Some boards feature 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.
