Lakduino UNO R5 is an Arduino Uno-compatible development board under the Lakduino brand, operated by Aptinex (Pvt) Ltd. The page indicates that purchases are redirected to the local distributor etusker.com. It is positioned as a cost-effective Uno-style board for getting started with Arduino, classroom experiments, and embedded prototyping. Note that the page title and packaging information use different terms such as UNO Rev4 and UNO R5, so the version naming is somewhat confusing.
On the hardware side, the board uses an ATmega328, runs at 5V with a 16MHz clock, and provides 14 digital I/O pins, 6 of which support PWM. It also includes 6 analog inputs and supports UART, SPI, and external interrupts. Power can be supplied via USB or the DC barrel jack. The recommended input range is 7V-12V, while the onboard regulator can handle 6.5V-15VDC.
Compared with earlier versions, Lakduino UNO R5 adds a CH340 USB-to-Serial chip, so users can upload sketches from the Arduino IDE over a USB Mini-B cable without needing an external serial adapter. It also adds SDA, SCL, IOREF, and reserved pins, and claims compatibility with existing shields while also supporting newer expansion boards that use these added pins.
The page describes it as the “World's Most Cost Effective Arduino Compatible UNO Board,” but does not provide specific pricing, stock status, shipping, payment methods, or warranty information. It only states that users will be redirected to a local distributor. As a result, its business model appears to be a one-time hardware purchase, but pricing transparency is limited.
Its strengths include strong Arduino Uno compatibility and a low barrier to entry through the Arduino IDE. The onboard CH340 reduces wiring complexity when uploading programs, and the board includes the common I/O, PWM, analog input, and communication interfaces expected from an Uno-style board. It also adds a resettable fuse for USB overcurrent protection. The downsides are limited documentation: no schematic, PCB files, sample code, driver links, or full technical support details are provided. It is also unclear whether the board is open-source hardware. CH340 drivers may need to be downloaded manually, which adds an extra setup step for beginners.
It is suitable for budget-conscious Arduino learners, school labs, electronics hobbyists, and developers who need to quickly validate sensor, actuator, robotics, or IoT prototypes. It is less suitable for teams that require strict industrial certifications, long-term supply commitments, or complete engineering documentation.
Based only on the crawled content, it is not possible to determine how stable access to lakduino.com or its distributor site is from mainland China, so this is marked as unknown.
