It is a hard, tedious job to solder a board with 140 components manually, but it is only two components on this that is hard to solder – one is the MCU or more correctly – I have chenged my soldering settings and this was straight up, no fuzz. I used higher temperature and it…
I bought a Monster8 board some time ago because I needed a control system with 5-7 RAMP’s for my PnP machine. I got a bit surpriced that no-one else uses this for OpenPnP, so I might be up for a surprice. But, lets get cracking. This board is very powerfully and much cheaper than the…
I have recently made two very similar CAN Boards, so it is a bit interesting to look at the differences since they have the same basic design. This first one is a M12 design (Above) – the name after the M12 connectors at right. It’s main purpose is to fit into a waterproof module with…
I designed a PLC with 3 x CAN ports earlier using M12 connectors and decided that I wanted a version that could be used on my desk or in a cabinet without the extra M12/Waterproof fuzz. It is the same design with a few tweaks: 3 x CAN ports on the motherboard Two motherboards or…
I recently made a Data Logger using a Nucleo-144 board and 16 bit ADC’s – the project works well and I am a bit surpriced over how easy it was to create both electronics, firmware and PC software, so I will attempt an even more advanced Data Logger illustrated below: A functional block diagram over…
This mornings catch… Made a new STM32H503CB base module. Swapped in STM32H503CB, a new 10 point 1.25 connector, my old SWD connector and a smaller SPI Flash. I also reversed 0402 trancient capacitors back to 0603 packages for now – I will reconsider moving to 0402 as I get the P&P working. The Molex 10p…
This is a PowerPoint mock-up. I just soldered om the PLCDCMotor board and im considering to keep the board as is with a less changes than I planned – the TTL connector at left can be used as is with a short 1:1 cable to a small board that convert the board to a stand-alone…
STM32H503CB is fastly turning into my favorite MCU for three reasons – it is fast, it is low cost and it has en extremely good IO routing system. It’s only drawback is 128Kb Flash and 32Kb SRAM, but it exist other MCU’s in the same series with more (that also cost more). That said it…
Using my M12 DCMotor driver as base I want to upgrade this board as described below – running motors are fun and this board is capable 10A (actually 2 x 10A) at 24V, so it is quite powerfully. This board is very capable as each driver privide two separate half H-Bridge circuits with current sensors…
This is a 4 x PWM or 2 x DC or 1 x Stepper motor driver. I have these boards already so I will solder one up for test later, but I will also design a new board with a few differences. MCU used here is a STM32G491Cx – these are good, but expensive so…
