## Description

An intelligent power board for the smôl ecosystem that boosts the voltage from one or two AAA or AA cells up to 3.3V. Features a TPS61200 boost regulator and an ATtiny43U microcontroller that enables deep sleep for the entire smôl stack — drawing just 12 µA in sleep mode. The processor board can instruct the power board to put the entire stack into deep sleep for intervals ranging from tens of milliseconds to several days, making battery life measurable in months rather than days. Key Features TPS61200 Boost Regulator – Steps up 1–3 V input to 3.3 V output ATtiny43U Microcontroller – Manages intelligent sleep/wake cycles (4 KB Flash, 256 B SRAM, 64 B EEPROM) 12 µA Deep Sleep Current – Ultra-low power consumption in power-down mode I²C Interface – Default address 0x50 smôl FPC Interconnect – 16-way 0.5 mm pitch flexible printed circuit stacking Specifications Output Current (max) – ~550 mA at VIN = 1.5 V; ~1500 mA at VIN = 3.0 V Regulator Quiescent Current – 55 µA Dimensions – 40.6 × 10.7 × 7.4 mm (L × W × H max) Weight – 1.6 g PCB Thickness – 0.8 mm Warning: This board has no reverse-polarity protection. Ensure your battery pack and connector have the correct polarity before connecting. Note: Current draw from a single cell will be approximately three times what the smôl stack draws at 3.3 V. For high-current applications (such as satellite communication boards), two AA cells are recommended for best results.
