This post is an update about my 4in1 blheli_s ESC previously known as uESC. I renamed it to tinyPEPPER and i just finished soldering a first prototype: This thing is TINY! Firmware flashing worked out of the box, blheli configurator allows to change all settings and i can use the betaflight gui to control the… Read More »

Why 1S??? I am currently working on a tiny 20x20mm F3 based flight controller and a tiny ESC in the same dimensions. As this ESC will be only good for 1S operation, i did some thrust tests with the new Racerstar 1103 8000KV motor from Banggood. I think my complete brushless setup will weight around… Read More »
I just finished a first port of betaflight — yay! (if you are wondering what a tinyFISH fc is, please have a look at the project page) Watch this video on YouTube The board shown here has not all components mounted yet and the black pinheader is just for debugging, it will be removed in… Read More »
I am currently building a tiny 4in1 Blheli_s ESC for a micro brushless copter. The final design will be 20x20mm, run blheli_s, support 1S @4A, and will probably weight less than two grams. In order to verify my hardware design i soldered a breadboard version of my circuit and started to port the blheli_s code… Read More »
While i was porting my OpenSky firmware to the D4R-ii receiver i made this collection of used parts and created a pin mapping. Maybe this is useful to someone in the future. Components used CPU: STM32F103C8 [Datasheet] EEPROM: 24C02 [Datasheet] RF Chip: CC2500 [Datasheet] HF-SWITCH: RDAES02 [Datasheet] PA/LNA: RDAT212 [Datasheet] RF Path The overall path… Read More »
In this post i am going to explain how to use my opensource firmware on a FrSky D4R-ii receiver. Please refer to the main page about my opensource project OpenSky for general information. Addition information on the board layout, used components, and the pinout can be found in this blog post. Pinout The default configuration… Read More »
In this post i am going to explain how to use my opensource firmware on a FrSky VD5M receiver. Please refer to the main page about my opensource project OpenSky for general information. Pinout The default configuration of my code uses the following pinout. If the board is in front of you with the leds… Read More »
In order to run betaflight with brushed motor control boards it is necessary to enable the normal PWM generatin mode. The information provided here was tested with version 2.9.1. The actual PWM frequency is configurable. As long as the mosfets switch fast enough use the highest possible value of 32kHz. Values below 20kHz will be… Read More »
The Problem The Skyzone SKY-02 FPV goggles are great for FPV flying and i really love them. Unfortunately they have one really annoying “bug”: You can not select if you are using Li-Po or Li-Ion batteries. As both have different discharge characteristics the low-voltage beep comes way to soon. Mine goes off at arount 3.75V… Read More »
