1. STM8S/STM8L Downloader gold-plated chip carrier, stable and reliable performance, It can package for most of TSSOP20 pin spacing of 0.65 mm STM8L and STM8S series chips of the burning, testing, operation, convenient and practical. 2. By SWIM interface, directly related to type of chip test, burning 3. Crystals can be free replacement by the user 4. All I / 0 by 2.54 mm double row needle derivation, convenient for the user to build circuit 5. Through the selection of four dial the code switch STM8S or STM8L burning Interface introduction 1. SWIM interface, can be download or test program 2. The MCU 20 pins all lead 3. With power indicator 4. Set the external interface of crystals Instructions: Based on the chip to hit four dial the code switch into the corresponding location, chip for STM8S series, switch position for U D D U. Chip for STM8L series, switch position for D U U D, which U dial up, D represents to stir. The 3.3 V ,SWIM, GND, foot in -LINK respectively connect with (+), SWIM, VSS (-), NRST foot of the board and then burning, support model for S003, S903, S103, L101, L151, L051 encapsulation for TSSOP20 STM8 series single chip microcomputer.
