Printed Circuit Boards from ALLPCB

For my development projects I recently ordered 10 pieces of 100x100mm double layer PCBs from ALLPCB and the process went great through and got 13 pieces as a bonus for only $5(!) including the express DHL delivery. Order details: 10 pcs of 100x100mm PCBs for TSSOP, QFN, DSBGA with 0.5mm pitch 0.2mm pads, 8 – […]

ARM Cortex-M4 core MCUs

Many embedded applications today can use 32bit microcontrollers based on ARM Cortex core which is beating down the 8bits prices and support. When you need more computing power including DSP instructions built in RISC, a huge amount of peripherals, timers, interfaces, high-pin count in FQP and BGA packages, up to 1MB of Flash and >128k […]

LPCxpresso in my mailbox !

Today landed! Credits go to NXP and EBV for their special offer of free LPCXpresso demo/evaluation boards  equipped with the target LPC1114 CortexM0 MCU. As NXP stated: “With over 45 DMIPS of performance compared to the sub-DMIP performance typical of 8-bit MCUs and to 3-5 DMIPS for 16-bit MCUs, NXP’s LPC1100L can not only execute […]

Mysterious signals at 126 MHz

While I was measuring a harmonic content of the signal from an oscillator in HF range, I tuned the great Kenwood TH-F7 TRX to VHF band. The receiver mode was set to USB and the frequency band to 108-138 MHz, where any jamming signal should not appear (air traffic control voice and data communications reside there). […]
