Part Comparisons
Side-by-side, datasheet-accurate comparisons to help you choose the right part.
W5500 vs ENC28J60 vs DM9051: SPI Ethernet Chip Comparison
All three add Ethernet to an MCU over SPI, but their architectures differ: the W5500 has a hardwired TCP/IP stack, the ENC28J60 is a 10 Mbps MAC+PHY needing a software stack, and the DM9051 is a 10/100M SPI MAC+PHY. Key comparison below.
View comparison →GD32F103 vs STM32F103: Replacement & Compatibility Comparison
The GD32F103 is the most common pin-compatible replacement for the STM32F103. Both are Arm Cortex-M3 in the same LQFP package and are largely register-compatible; the main differences are core clock and a few porting details.
View comparison →RV-3028-C7 vs DS3231 vs PCF8563: I²C RTC Comparison
All three are common I²C real-time clocks with different positioning: the RV-3028-C7 targets ultra-low power, the DS3231 wide-temperature precision (TCXO), and the PCF8563 basic low cost. Compared by key metric below.
View comparison →GD25Q vs W25Q: SPI NOR Flash Replacement Comparison
GigaDevice GD25Q is the most common second source for the Winbond W25Q — both are standard JEDEC SPI NOR with the same pinout and command set. The main difference is the JEDEC manufacturer ID.
View comparison →GD32F407 vs STM32F407: Cortex-M4 Replacement Comparison
GigaDevice positions the GD32F407 as an STM32F407-class alternative — both are 168 MHz Arm Cortex-M4 (with FPU/DSP) with aligned packages. It is a functional alternative (design-in), not a register-identical drop-in.
View comparison →WizFi360 vs ESP8266: Wi-Fi Module Comparison
The WIZnet WizFi360 is widely used as a footprint-compatible alternative to the ESP8266 / ESP-12F — both are 2.4 GHz 802.11b/g/n with a UART AT-command interface. Confirm pin mapping and AT command-set differences before swapping.
