The minimum system performance requirement for DSP5509 is the lowest, and it is OK to run a minimum program. For details, please add Q: 76777689, label: 5509. There will be a generous reward! I forgot...
[table][tr][td]It oscillates at about 50% duty, input 8V, output 4V; or input 15V, output 7.5V (rough estimate); there is no problem if the duty is lower or higher than this. Voltage mode, built-in ty...
Good blow, I'm a novice! I want to use a microcontroller to control the heat blocks and the like through relays. If I use a HK400F relay, can I directly connect it to 220V?
How do I connect those term...
The introduction looks very impressive, but I went to the official website to look for it, but couldn't find any information. It is said that this little guy uses Nordic's nRF52811 chip....
