Figure 2-2. C51/C251 Demo Board powered by J1 with a non-rechargeable battery on J2
n Power connector J1 or battery connector J2 may be used to power the board.
n On J2 connector a rechargeable battery or a non-rechargeable battery may be used.
n In case of rechargeable battery usage on J2, if J18 is ON the battery is charged when
the board is powered by J1.
n Board may be powered by J2 for about 10 hours with one new non-rechargeable
battery.
Note:
J18 must be Off, when the board is powered by J1 with a non-rechargeable
battery connected on J2 (see figure 3).

– Configure hardware in Page Mode or Non Page Mode.
– for C251 microcontrollers. For C51 products, the configuration must be set to
Non Page Mode.
n
Synchro IN
– Used to connect several C51/C251 Demo Boards together, provides global
reset / interrupt for all connected C51/C251 Demo Boards.
n
Synchro OUT
– Only one power supply is needed but it may be able to deliver enough
current to supply all the C51/C251 Demo Boards.
– There are no rules to connect two boards together anyone of the two DB9
may be used.
n
RS232
– Used to connect a terminal or through an RS232 serial communication port.
– This serial port can be used for displaying messages or for programming
external Flash memory.
Note: The cable that connect this RS232 Connector MUST be a pin to pin cable.

С самовосстановлением предохранителя, короткого замыкания и перегрузки по току! Даже неправильное использование, приводящее к короткому замыканию платы развития, это не повредит вашему компьютеру! Сбрасываемый предохранитель автоматически отключит питание, дождитесь короткого выпуска автоматически после восстановления питания!
Поддержка микроконтроллера серии 51 STC89C52, STC12C5A60S2, AT89C51, AT89C52, AT89S51, AT89S52 наиболее часто используется. Кроме того, для поддержки других 40 футов микроконтроллера серии 51 и ATmega16! STC89C52, STC12C5A60S2 может серийный прямой загрузки программы для, AT89S серии микроконтроллер нужно специализированное Программирование загрузки программы с USBISP программа менеджера загрузки, AT89C серии микроконтроллер. ATmega16 использовать нужно использовать пластину адаптера, программа загрузки требует USBISP загрузчик!
Обратите внимание:
1. Заводская испытательная стенда печатной платы для обеспечения нормального физического подключения!
2 большой коврик разработан специально для любителей DIY, сварка очень легко!
3. В процессе сварки требуется внимание к светоизлучающим диодам (т. Е. Светодиодный светильник более с двумя запасными) и не перегревается чувствительных к температуре компонентов, таких как, быстрее, В противном случае он будет гореть светодиодный светильник. Мы гарантируем, что все компоненты, если какая-либо сварка не удалась, отладка не работает и т. Д., не обеспечивают замену (из-за наличия технологии сварки), но покупатель оплачивает гарантию доставки.
Эта цена как показано на всех устройствах (пустая плата PCB и сварочные компоненты платы включают вставные устройства: крышка перемычки, 11,0592 м осколок кристалла MAX232 каждый), не содержит микроконтроллер, линия электропитания и линия загрузки
