The STM32L011G4U6TR: Housed in a 28-lead UFQFPN measuring 4x4 mm (supplier device package 28-UFQFPN), this is a compact, low-profile package for space-constrained designs.
Connectivity covers I²C, IrDA, SPI, and UART/USART — enough for serial sensor interfaces, display modules, or wireless module control. The 10-channel 12-bit ADC reads analog inputs directly.
