This module involves the design of a keypad lock system. It utilizes an ATMEGA328P microcontroller, buzzers, LEDs for indicator functions and a 4x3 matrix keypad. An in-circuit serial programming (ISP) header is also present for programming the microcontroller. #template #lock #keypad #reusable #module #simple-embedded #microchip #arduino #atmega328 #TPS613222A #ISP #buzzer #sublayout

CONN MOD JACK RJ45 TH The HR911130A is a single-port RJ45 MagJack® Ethernet connector from HanRun Electronics with integrated Ethernet isolation magnetics and green/yellow status LEDs in a compact through-hole, right-angle package. Per the datasheet, it is designed for 100/1000Base-T Ethernet applications and meets or exceeds IEEE 802.3ab requirements, simplifying PCB layout by eliminating the need for external isolation transformers. Key Features Single-port RJ45 connector with integrated Ethernet magnetics Supports 100/1000Base-T Ethernet applications Integrated green/yellow link/activity LED indicators Shielded metal housing for improved EMI performance Through-hole, right-angle PCB mounting Compliant with IEEE 802.3ab Ethernet requirements 1500 Vrms isolation between UTP side and chip side Integrated 4 x 75 ohm termination network and 1000 pF / 2 kV capacitor shown in datasheet Reduces external component count and PCB space RoHS compliant Shield / mechanical notes: footprint pads 15 and 16 are plated through-hole shield/mechanical tabs; pads 17 and 18 are non-plated locating holes. The current schematic exposes pins 1-14 as electrical terminals; shield tabs 15/16 are documented as physical shield/mechanical tabs and are not exposed as separate schematic terminals. Ideal for routers, switches, embedded Ethernet devices, industrial control, IoT equipment, and other 100/1000Base-T network interfaces. #HR911130A #HanRun #RJ45 #MagJack #Ethernet #LAN #IntegratedMagnetics #NetworkConnector #PCB #EmbeddedSystems #IndustrialElectronics #IoT #ThroughHole #IEEE8023ab #1000BaseT
