The Whadda WPB100 ATmega328 UNO DEVELOPMENT BOARD (Arduino® Uno compatible) is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; connect it to a computer with a USB cable or power it with an AC to DC adapter or battery to get started. * Microcontroller: ATmega328 * Operating voltage: 5 VDC * Input voltage (recommended): 7-12 VDC * Input voltage (limits): 6-20 VDC * Digital I/O pins: 14 (of which 6 provide PWM output) * Analogue input pins: 6 * DC current per I/O pin: 40 mA * DC current for 3.3 V pin: 50 mA * Flash memory: 32 kB (ATmega328) of which 0.5 kB used by bootloader * SRAM: 2 kB (ATmega328) * EEPROM: 1 kB (ATmega328) * Clock speed: 16 MHz * Length: 68.6 mm * Width: 53.4 mm * Weight: 25 g https://elecena.pl/product/27149361/whadda-wpb100-atmega328-development-board 2024-11-06 https://elecena.pl/product/27149361/whadda-wpb100-atmega328-development-board 2026-03-28
