Kufotokozera kwa pini:
Dzina la ma pini Kufotokozera
5v Mphamvu mawonekedwe Mphamvu gawo
Lumikizanani ndi DC5v
GND
Mawonekedwe a VDD TTL UART Mawonekedwe amtundu wa TTL UART, mutha kulumikiza MCU ngati 51MCU kapena ARM, kapena MSP430 mwachindunji. Pini ya VDD imagwiritsidwa ntchito kufananiza voltagndi TTL.
SIM_TXD
SIM_RXD
GND ngati pini iyi sinagwiritsidwe ntchito, khalani otsegula
RST RST gawo, ngati pini ili yosagwiritsidwa ntchito, sungani lotseguka
