2.51 microcontroller development board using STC89C52RC-LQFP-44 main control chip, on-board USB to TTL serial chip CH340, easy to download programs and serial communication experiments.
3. Micro USB interface, comes with a download circuit a cell phone data line can be downloaded.
4. No welding pin, easy to design their own use, can be upward or downward welding pin, connected to the 2.54 pitch multi-purpose board and other applications.
5. Ultra-low power consumption design, normal operating mode 4mA-7mA, power-down mode can be woken up by an external interrupt, suitable for battery-powered systems, such as water meters, gas meters, portable devices.
Operating voltage:5.5V-3.8V(5V microcontroller)
Operating frequency range:0~35MHz.
On-chip integrated 1280 bytes or 512 bytes RAM
Ultra-large capacity SRAM, up to 1280 bytes SRAM
Strong anti-interference.
1.Anti-static
2.4KV fast pulse interference (EFT test)
3. Wide voltage, not afraid of power jitter
4.Wide temperature range, -40℃-+85℃.
Ultra-low power consumption
1. Power-down mode: typical power consumption <0.1uA
2. Normal operation mode: 4mA-7mA
3. Power-down mode can be woken up by external interrupt, suitable for battery-powered systems, such as water meters, gas meters, portable devices, etc.
4. Programmable in the system, no need for programmer and emulator, can be upgraded remotely.
Size: 61mm*38mm
1. On the P0 port pull-up resistor, if you use the STC89C52 version, P0 port if you do the external output driver, you need to external pull-up resistor, do the general LCD bus such as LCD1602, LCD12864 bus, can be used directly, no external pull-up resistor.
2. Different batches, product appearance and pin color is slightly different, the same function!

Do not dismiss your dream.
To be without dream is to be without hope.
To be without hope is to be without purpose.
Do not run through your life so fast that you forget not only where you have been, but also where you are
going.
Life is not race, but a journey to be savored each step of the way.
