3.1 Board features (connectors and jumpers)

www.nichicon.com COPYRIGHT © 2024 NICHICON (AUSTRIA) GMBH 4 1. Description The Nichicon EHV 2107.111 evaluation board is a printed circuit board assembly (PCBA) featuring all required components to quickly operate and evaluate an energy harvesting concept using an ultra-small lithium titanate battery (LTO), so-called “SLB series” as the energy storage device. As for the harvesting, the power management is operated with the integrated circuit (IC) AEM30330 from E-Peas. 1.1. Why using an E-Peas PMIC? The E -Peas features a n ultra-low power and high- efficiency PMIC for energy harvesting where users can configure specific setups, that allows the usage for a wider range of IoT harvesting applications:  Indoor solar harvesting (DC source)  Vibration harvesting from low frequency (AC source)  Open circuit voltage sensing for Maximum Power Point Tracking (MPPT) between 35% to 80%  MPPT voltage range 100mV to 4.5V  Cold start (harvesting from 275mV and 3mW)  Output current 30mA (low power) or 60mA (high power)  Load voltage 1.2V to 3.3V  Overcharge / discharge protection  Quiescent current as low as 875nA  Ultra-low-power For more information on the PMIC, please visit: AEM30330 product brief: PB_AEM30330.pdf (e-peas.com) AEM30330 datasheet: DS-AEM30330-v1.4.pdf (e-peas.com) 1.2. Why using LTO batteries from NICHICON?  Ultra-low harvesting charge with i.e. 0.01C (5µA) due to low internal resistance  Rapid charge/discharge with 20C  Increased charge/discharge cycles (up to 25.000 cycles) Figure 1 - E-Peas AEM30330 schematic (simplified)

www.nichicon.com COPYRIGHT © 2024 NICHICON (AUSTRIA) GMBH 5  Very low self-discharge and operation at as low as -30⁰C  Extremely safe against rupture / ignition (UL1642 / IEC62133-2:2017)  Maintenance-free  0.35mAh (3.3x9mm L) up to 150mAh (12.5x40mm L) For more information, please visit our dedicated site: SLB series: Nichicon Small Lithium Titanate Rechargeable Batteries (nichiconbattery.com) 2. Product specification  Space for up to three parallel SLB batteries (no series connection available)  USBC charging with up to 20C / charge current can be set via switch  PMIC E-Peas AEM30330 with configuration jumpers (i.e. MPPT, load configuration etc.)  Harvesting source from either DC (i.e. indoor PV) or AC (i.e. piezo) available  11 measure and test point for evaluation purposes  DC and AC harvesting sources  PCBA size: 110 x 60mm 3. User Guide The PCBA was initially designed as a harvester demonstration board including CO2 sensor (CozIR -Blink), a gas sensor (Bosch BME688) and a Light sensor (LITE -ON LTR-329ALS) with data transmission via BLE /LoRa (Insight ISP 4520). For this evaluation board variant, th ese components have been removed from the PCBA so that individual harvesting solutions can be designed. Figure 2 - PCBA assembly
