Samsung LPCAMM integrates LPDDR RAM on removable modules

Samsung LPCAMM

Samsung has unveiled a new type of removable memory module called the LPCAMM (Low Power Compression Attached Memory Module) with LPDDR designed for PCs and laptops, and the company expects them to eventually be used in servers found in data centers. I would also not be surprised to find them in embedded systems in the future, for example in an updated COM Express standard. Laptops typically come with either low-power DDR (LPDDR) soldered to the motherboard or SO-DIMM modules with DDR memory chips, but there weren’t any removable modules with low-power memory so far, and Samsung LPCAMM changes that. The new LPCAMM module will initially be fitted with LPDDR5X chips and deliver a 50% performance boost (up to 7500 MT/s), improve power efficiency by 70%, and reduce the mounting area by 60% (78 x 23mm) compared to SO-DIMM modules A main factor in reducing the area required is that two […]

Review of ALLPCB PCB manufacturing services with an ESP8266 board (Sponsored)

E66R Transmitter PCBA

ALLPCB, a PCB manufacturer based in China, has offered us to review their PCB manufacturing services. We’ve taken them up on their offer and will report our experience with the ordering process, shipping, and the board itself, in this review. We will be using the E66 Transmitter board based on an ESP8266 module, and designed to read values from an I2C sensor and send them over RS485 using the Modbus RTU protocol for a range of up to 1.2 km. Since the E66 Transmitter can also connect to WiFi thanks to the ESP8266 module, Modbus TCP is also supported. Since we have our PCB design ready, we can go to the ALLPCB website to start the ordering process. We just had to upload the Gerber files, and then select parameters such as the number of boards, the number of layers, thickness, material type, and whether to include a Stencil or […]

Raspberry Pi Pico to Arduino Uno adapter relies on “FlexyPins” for castellated holes

Raspberry Pi Pico Arduino UNO adapter FlexyPins

Solder Party’s “Raspberry Pi Pico to Uno FlexyPin Adapter” transforms the Raspberry Pi Pico into an Arduino UNO without soldering the board directly or using headers, but instead relying on FlexyPins flexible pins to attach the Pico board to the adapter using its castellated holes. The end result is basically the same as for the WisdPi ArduPico board, except the Raspberry Pi Pico is soldered to the main PCB on the latter, but it can be easily removed from the Solder Party’s Uno adapter board to be replaced with another compatible model, e.g. Raspberry Pi Pico vs Pico W. The FlexyPins can be used with any board or module with castellated holes, but it’s obviously especially useful for castellated modules without through holes, for example, to easily program a bunch of ESP32 modules. You’ll first need to get a few FlexyPins as shown below. Then solder them to a compatible […]

VL53L7CX Time-of-Flight (ToF) sensor offers camera-like 90° field of view

VL53L7CX wide FoV ToF sensor

STMicroelectronics VL53L7CX is the latest FlightSense multi-zone Time-of-Flight (ToF) distance sensor from the company with the main highlight between its camera-like 90° diagonal field of view, derived from a 60° x 60° field of view… This is a significant improvement over the 61° diagonal field of view of the previous generation ToF sensors such as the VL53L8 or VL53L5CP,  and the wider field-of-view is said to bring “lifelike situational awareness” to applications like home automation, computers, house appliances, robots, and industrial equipment with full-privacy since ToF sensors do not capture photos or videos like traditional cameras. STMicro VL53L7CX key features and specifications: 940 nm invisible light vertical cavity surface emitting laser (VCSEL) and integrated analog driver 60° x 60° square field of view (FoV) (90° diagonal) using diffractive optical elements (DOE) on both transmitter and receiver enabling square FoV Receiving array of single photon avalanche diodes (SPADs) Multizone ranging output […]
